In this section we are going to look at the next stage in the process of finding information. We will be introducing the sorts of information systems you might use. Some of these are organised, like library catalogues and databases, whilst others, such as the World Wide Web, are not. We will be showing you how to move from knowing broadly what information you are looking for, to knowing where you are likely to find it, and to planning how you will go about retrieving it. NB – If you plan to complete all the activities in this section you will need to allow between one and two hours to finish everything. Some activities will require you to use paper and pen to make notes or record your thoughts. Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 4 of 33 Topic 2: Describing information Library catalogues and databases are two systems that are widely used to store information. The basic principle behind library catalogues and databases is that someone has collected resources or pieces of information together, identified and described them and then organised them in a systematic and consistent way so that you and I can find them. Activity: Identifying and describing things Question So, how might information sources be identified and described? Imagine that you wanted to identify and describe the items below in order to organise them for others to use. What criteria or categories might you use? Make a note of these and then look on the next page for our suggestions. Figure 1: Information sources Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 5 of 33 Discussion There are many possible terms that could be used but we thought you might decide to use: Author Artist or composer Title Publisher or organisation Date Description of what it is, i.e. its format Description of what it is about – this might be a summary – also called an abstract – of the content of the item, or it might be a list of the topics covered (sometimes called descriptors, keywords or topic-words), or it might be both. Reflection There are no hard and fast rules about which possible criteria are more useful than others; the context in which they are to be used will be one deciding factor. You may like to reflect on whether you would use any of the terms listed below and when and where they might be meaningful: Author date of birth Author nationality Type of binding/packaging Colour of resource Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 6 of 33 In a database or library catalogue, each of the categories such as ‘author’ or ‘title’ is called a ‘field’ – there are likely to be others but these are the most important ones to be aware of when you are carrying out a search for a book or a journal article. The collection of several fields of information associated with each individual book or journal article is called a ‘record’. It is these records which make up the contents of library catalogues and databases. Activity: Looking at item records What kind of information would appear in the records for these items? Would the same information be required for each? When you have decided, go on to the next page to read the actual records.

What is a database? Many of you are probably familiar with the idea of a ‘database’. Organisations often hold information about individuals in a database. For example, your doctor or dentist will hold your records in a database as will banks, government departments, phone companies etc. A database is a way of storing, indexing, organising and retrieving information. You may have created one yourself to keep track of your references – or your friends' names and addresses. The specialised databases we can use to search for references to journal articles are called 'bibliographic' databases (because they contain information in summary form about books and journal articles). They are electronic indexes to the contents of thousands of journals, and, in some databases, books. Some are general and cover all subject areas while others are more specialised and concentrate on a particular discipline. What do they contain? This varies – some contain references to articles including abstracts (summaries of the content of an article). Others will include or link to the full text (the content) of the article too. Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 10 of 33 Why use them? They can be a very quick means of accessing thousands of references to academic material, at the click of a mouse. The fact that the information is in the databases means it has usually gone through some selection or reviewing process by virtue of its publication in an academic journal – so the information is likely to be of high quality. Activity: Looking at databases To see the opening screens of some databases, click on one of the links below (OU login required). You don't need to look at them in great detail – this is just to give you an idea of what they look like. FirstSearch (click on the ‘List all Databases’ button to choose one of interest to you) Web of Science Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 11 of 33 Topic 4: Library catalogues What do these items all have in common? Figure 2: Catalogues They are organised lists of things. They are all different types of ‘catalogue’ (‘A complete list of items, typically one in alphabetical or other systematic order’ – Oxford English Dictionary). Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 12 of 33 Library catalogues – what do they contain? Library catalogues are databases containing information which relates to material located in a particular library. A library catalogue will hold information about individual items, for example, where in the library you will find the item, how long you may borrow it for and if there is more than one copy. It also holds information about what items are available in which subject areas and where in the library you will find those items. Libraries also use online catalogues to record what is available. These are sometimes referred to by the acronym OPAC (Online Public Access Catalogue). Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 13 of 33 Why would you use a library catalogue? Activity Think about why you might use a library Reflection We thought you might want to use the catalogue to: check the full details of something you want to borrow or buy find out about material that is kept by the library but is not available, e.g. it is ‘on loan’ to someone else, or it is kept in another location use your time in the library more efficiently, by finding out what is held in a library before looking on the shelves Or, you may have decided that you would not need to use a library catalogue, as you would prefer to ‘browse’ the shelves in person or do your searching remotely via the online catalogue. Using a catalogue can help you to save time, both before visiting a library and while you are working in a library. If you have access to the Internet you may be able to check your library catalogue online, before making a visit. In this way you can avoid making a journey to a library that does not have the material you are looking for. If you do not have access to the Internet you can ring the library and they may be willing to check the catalogue for you. They will not be able to check a long list, so ask about a few key items. You can then decide if a visit is worthwhile. When you are actually in the library, you might like to use the catalogue to check for further details, such as where on the shelves items are kept, and whether they are available to borrow. Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 14 of 33 Topic 5: World Wide Web What do you think about the web? The Internet is a worldwide network of interconnected computers and all the world's publicly accessible websites (and other information sources that web browsers can access) constitute the part of it known as the ‘World Wide Web ’. These generate strong opinions. Look at these quotations, for example, ‘The Net is a waste of time, and that's exactly what's right about it.’ Quote from William Gibson, science fiction writer. ‘The Internet will do for personal networking what the microcomputer did for personal computing.’ Source: ‘Internet to grow ten-fold by year 2000 – claim.’ Internet Business News, Jan 1 1995. ‘By the year 2003, every person on the planet could be on the net. At this point the prime use of the Internet will not be surfing, cruising or riding – it will be learning.’ Source: ‘All human life is here...’ The Herald (Glasgow), Dec 20, 1994. Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 15 of 33 Reflection Spend five minutes jotting down the first things that spring to mind when you see the term ‘World Wide Web’. Have you used it for your work, or your studies? If so, how did you get on? Did it help? How? How did it not? In our experience, using the World Wide Web can enable us to reach new information we would not find elsewhere but it can also be frustrating as we do so. What is the World Wide Web? The World Wide Web is increasingly part of our everyday lives. It is estimated that worldwide there are presently something in the region of 1.1 billion Internet users, which is nearly 20% of the world's population. ‘World Wide Web’ and ‘Internet’ are terms you might hear used interchangeably, but they actually refer to two different things. The Internet is the interconnection of computer networks across the world. If you've got an e-mail address, you're using the Internet when you send a message – so the term Internet is more about structure, and how such communication happens. The web is all of the publicly accessible websites in the world, in addition to any other information sources that web browsers can access e.g. newsgroups. Accessing the web is just one way of using the Internet. The web is another useful source of information but it is quite unlike library catalogues and databases in that it isn't so neatly organised. On the web you can look at information which can be in the form of text, images, video, or audio. Websites are linked together using a system called hypertext which allows you to move from site to site. You are using something called a browser, probably Chrome, Firefox or Internet Explorer, to access this information. Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 16 of 33 Activity: What does the Web contain? The Web contains all sorts of things. Try clicking on the links below to access the live versions of four very different web pages. Think about the kinds of information you can find on these pages, and the use you might get from them. BBC News site Argos website British Library Uluru & Surrounds website Why use the web? We have already seen that the web is a source of many different sorts of information. The information itself varies greatly in quality and usefulness. For academic work you will find that increasingly library catalogues are accessible online. There are many online journals too, and some publishers now offer online access to journals previously only available in print format. Increasingly too, the web is used as a delivery medium for official information like government publications and public records. Timetables and professional directories may also be useful as you develop study and research plans. You can also access bookshops via the web and buy books and other resources online. Newspapers and magazines online may provide less reliable but nonetheless useful information. Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 17 of 33 The more the better? New sources of information are emerging as users start to exploit the capabilities of the web. In particular there are blogs (personal online 'web-logs'), like online public diaries. You may find useful information on these but you need always to check that it is reliable and accurate and available for re-use. Your module may also require you to use a blog as a means of sharing your reflections on learning with other students as your module progresses. Whatever you use it for, you need to remember that the web is a vast and useful resource but the information you can find there is only as good as the providers make it. Sometimes there will be questions about how accurate or how balanced that information is. You may need to do some further investigations before using the material for your studies. Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 18 of 33 Topic 6: Which tools to use We have identified some of the tools you might find useful when you are looking for information – the World Wide Web, library catalogues and databases. Each approach is useful in different circumstances – you may use just one of them, or all three, depending on what you want the information for. Activity: Which tool would you use? Imagine you are writing a short assignment, due in next week, on GM food and you want to find a quote from someone else to back up one of your points. Which of these tools might you use? World Wide Web Library catalogue Database If, however, you were writing a long assignment (say 5000 words) on GM food, your use of the tools might be quite different. Web Library catalogue Database Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 19 of 33 Discussion: The tools we would use If you were writing a short assignment, you might use the tools in the following ways. Websites You might try looking on the web for what has happened in the last week in the news about GM food using an online newspaper or magazine. Library catalogue You might try using a library catalogue to look for a book on GM food – you might be able to pop in and have a quick look at it. Database You would probably only use databases to look for references to journal articles if you had time to do it. Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 20 of 33 If you were writing an assignment, you might use the tools in the following ways. Websites You might try looking on the web for what has happened in the last week or last few months in the news about GM food using an online newspaper on the web. You might try looking for what a particular organisation thinks about GM food using the web. You might try looking at what political parties have to say about GM food using the web. Library catalogue You might try using a library catalogue to look for more than one item on GM food. There may be some recently published books or conference papers in the library. Database You might try using a database of journal articles to look for what research there has been over the last few years into GM food. Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 21 of 33 Reflection Look carefully at the discussion on the previous page. Why would different items be useful for different lengths of assignment? What is different about the information you might collect for the long assignment? So, different tools will be useful to you in different ways depending on what you are looking for. Before you start using any of these tools, you need to have a good idea of what you are looking for. The next Topic will show you how to translate your broad search questions into specific search strategies. Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 22 of 33 Topic 7: Planning a search Scenario Early on in her project, Mary (studying on a Post-Graduate Science course) came up with a series of questions which had helped her to identify exactly what it was about GM food she was looking for. One of the questions she had ended up with was: ‘Is there research evidence on any health effects of eating GM foods?’ But how was she going to get from knowing what she was looking for, to getting the information itself? She couldn't go into a bookshop or library, armed just with her question, and expect to find a book with all the answers in. What she needed to do was to break her question down, to pinpoint the range of ideas it included. This would then enable her to look for specific material. She needed to translate the questions into a ‘search strategy’. Translating your question into a search strategy or statement is an important first step in tracking down the information you need. Developing a search strategy starts by thinking about the kinds of words related to your topic that you might expect to find in books or in newspaper articles. Carefully considered keywords and/or a good search statement can be applied to whichever sources you might decide to use. They will be equally effective with such resources as specific computer databases, library catalogues or online journals etc. Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 23 of 33 Our student used the framework given below to help her when planning her searches. She chose to write it down as it helped her to get a concrete picture of what she was looking for, and meant she didn't miss anything out. The framework is given in the list below, followed by Mary's comments relating specifically to her search about GM foods. Ask yourself, what do I need to know? Mary's comments “I want to know whether there is any information on the health effects of eating GM foods.” Break the topic down into its broad areas or concepts. You will usually find that your question breaks down into a couple of ideas or concepts. Mary's comments “Genetically modified foods – eating – health” Is there a very specific word or phrase that you are looking for? If there is a commonly used and recognised term for your topic, use it, as most authors will also have used it, and it will make your search more specific. Mary's comments "Genetically modified food" is already quite a specific term – I can't think of any other way it might be expressed. Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 24 of 33 Think of some alternative words for the words you have chosen – for instance, ‘young people’ and ‘adolescents’ mean roughly the same thing. So that you don't miss anything, remember: plurals child, children abbreviations UK, United Kingdom variations in spelling colour, color, specialised, specialized Variations in terminology used in different cultures and countries – for instance, ‘children with emotional and behavioural problems’ (UK) are referred to as ‘maladjusted children’ in the US. This will help to ensure that you find things that an author might have referred to using different terms. But don't worry if you can't always find any sensible substitutes for the words you have chosen – there might not be any. Mary's comments “Genetically modified food or foods, GM food or foods. Eating, consumption, consuming. Health effects, side effects, consequences, harm, risk” Are any of the words vague or ambiguous? If they are, cut them out – it is important to be precise so that you only find what is relevant. Mary's comments “I'll take out the health effects bit – the consumption and side effects words seem to sum up better what I mean.” Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 25 of 33 Next try writing out your request in full. Mary's comments: “I want to find out about the consequences, harm, risk or side effects – of eating, consuming or the consumption of – GM or genetically modified food or foods.” Further questions are part of the framework as follows: Are there any geographical or date limitations you need to build in to your search? (E.g. are you looking for the worldwide or European perspective? Are you interested in historical or very current material?) Does your statement make sense? Are all the words that relate to each other in the right place? If they are, you are ready to choose your sources and start searching. On the next page, you will find a checklist that you can use to help you to plan your searches. Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 26 of 33 Checklist for planning your search 1. Ask yourself, what do I need to know? 2. Break the topic down into its broad areas or concepts. You will usually find that your question breaks down into a couple of ideas or concepts. 3. Is there a very specific word or phrase that you are looking for? 4. If there is a commonly used and recognised term for your topic, use it, as most authors will also have used it, and it will make your search more specific. 5. Think of some alternative words for the words you have chosen – for instance, ‘young people’ and ‘adolescents’ mean roughly the same thing. So that you don't miss anything, remember: Plurals – child, children Abbreviations – UK, United Kingdom Variations in spelling – colour, color, specialised, specialized Variations in terminology used in different cultures and countries – for instance, ‘children with emotional and behavioural problems’ (UK) are referred to as ‘maladjusted children’ in the US. 6. This will help to ensure that you find things that an author might have referred to using different terms. But don't worry if you can't always find any sensible substitutes for the words you have chosen – there might not be any. 7. Are any of the words vague or ambiguous? If they are, cut them out – it is important to be precise so that you only find what is relevant. 8. Next try writing out your request in full. 9. Are there any geographical or date limitations you need to build in to your search? (E.g. are you looking for the worldwide or European perspective? Are you interested in historical or very current material?) Does your statement make sense? 10. Are all the words that relate to each other in the right place? If they are, you are ready to choose your sources and start searching. Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 27 of 33 Topic 8: Choosing resources The next step will be to match your search statement against relevant, appropriate resources in your subject area. If your search statement was: I want to find out about the consequences, harm, risk or side effects – of eating, consuming or the consumption of – GM or genetically modified food or foods. You might be looking for: ideas and opinions – expert opinion, opinions of pressure groups, public opinion, opinion of companies involved in trials, opinion of governments and other organisations; research results – medical experiments, scientific information; history – where the debate began and why. You will need to have a clear idea of what it is about your topic that you want to know. Then you should be able to look closely at the individual resources, such as databases, on offer in your subject area, to see what information they contain. It is very likely that you will have to apply your search statement to different sources to get the range of information you need. Keeping the particular aspects of your topic in mind, you should then try to see how the resources measure up against your topic and decide which ones are going to provide you with the information you are looking for. Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 28 of 33 Which sources are you going to try? We have decided to look for: ideas and opinions research results history/background related to our search statement: “I want to find out about the consequences, harm, risk or side effects – of eating, consuming or the consumption of – GM or genetically modified food or foods.” What are the resources available to us and how might they help? Start by thinking about sources you have already learned about and how they might help. If it is helpful to you, make some notes about these. Once you have thought for a while go to the next page and consider the options that we have found. Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 29 of 33 Look at the descriptions of the sources below, all of which are available on Library web pages, and think about how they ‘measure up’ to the topic. Which do you think might be the most useful information sources to try? Make some notes about the reasons for your opinions on these sources. Click on each information source to find out more about it. Information will open in a new window, which you will need to close to return to this screen. You may need an OU login to access these. 1.

Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 30 of 33 Discussion Arts and humanities citation index Title, keyword & citation searching of 1,160 journals, 1975 onwards. No – this is a database of articles relating to Arts and humanities - our topic doesn't fall into this area. Social Sciences Citation Index. Provides access to the bibliographic and citation information of over 1,950 of the world's leading social sciences journals, 1956 to the present. No – this database relates to social sciences – our topic doesn't fall into this area. Science citation index expanded. Title, keyword and citation searching of 6,650 journals in science and technology. From 1899 onwards. Yes, definitely. It's a science database. This should provide us with some articles on research results. Nexis UK. The full text of newspapers and other news sources worldwide; also contains company data and business directory information. Yes, definitely. It's a database of news. This should provide us with ideas and opinions that have appeared in the media. Academic Search Complete (EBSCO). Full text of nearly 6,000 journals, including more than 5,000 peer-reviewed journals. Yes, probably, as it covers some science material. However, as it indexes nearly 6,000 titles across a number of disciplines, we will probably have to use another source too. Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 31 of 33 MedlinePlus. Yes, definitely. This should provide us with some medical evidence. GeoRef. Access to the earth sciences literature of the world. Contains references to geoscience journal articles, books, maps, conference papers, reports and theses, 1785 onwards. No – This database covers science, but not the branch of science we are looking for. Government web pages. Yes, definitely. This might provide us with some useful background information on government policy, plus an insight into government opinion. My local library catalogue. Yes, definitely. There may be some useful books about the origins of the GM foods debate, plus they may have some of the journal articles. Deciding where to look for information can be the most complicated part of the searching process because there are so many resources on offer – in this example, we have already come up with 6 possible resources which might help us with our enquiry. You will need to weigh up one resource against another, using its description, if there is one, and prioritise, particularly if you are working to a deadline. You may find that a resource that you have chosen might not give you the results that you were expecting. Look at the results you find – might you be able to alter your search statement (take a word out or put a new one in) to get more accurate results? Try this before moving on to a different resource. Safari: Section 3: Planning a search Copyright © 2014 The Open University Page 32 of 33 Topic 9: Summary In this section we have introduced databases, one of the main ‘tools of the trade’, and have thought about what they contain and why we should use them. We have also highlighted the World Wide Web as an information source. We explained how to translate a search question into a search strategy, in preparation for using the tools. Then we looked at trying to match a search statement with appropriate resources. Activity: Applying what you’ve learnt Jot down what you think are two of the most useful things you have learnt in this section. How are you going to apply these to your own work or study? Finally, we hope that this section has helped you to start thinking about planning your searches in a systematic way, from deciding what it is that you are looking for, to choosing the best sources to use. These are really useful skills to master, as they can be applied to almost every situation in which you may need to search for information.
