This section will be especially useful to you if you are involved in project work or longer TMAs (Tutor Marked Assignments). 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 6: Organising information Copyright © 2014 The Open University Page 4 of 30 Topic 2: Why organise? Our Science post-graduate student, Mary, has identified lots of sources to help her with her assignment on GM foods and feels she is almost ready to write it. However, as she has been sifting through the pile, she has discovered some puzzling things amongst the materials she has collected in her file. Activity You will be presented with three examples of how Mary has recorded her sources on GM foods. For each example identify any issues Mary might encounter, if she wants to use them for her assignment. Makes some notes on your thoughts. There is a discussion after the third example. Example 1 Mary has written the following in her notebook: “Chapter five assessing the risks from 1989 report – good background stuff Quote "During the course of our study a number of authoritative reviews have been published of the risks associated with the release of GEOs. These include a statement by committees of the International Council of Scientific Unions and reports by the United States National Academy of Sciences..." * Page 38 Quote "A release licence should be required before a release may take place." Licences should be issued by …” Safari: Section 6: Organising information Copyright © 2014 The Open University Page 5 of 30 Example 2 Mary has photocopied two pages from a book or a journal. When the item was photocopied, the contextual information (title, author, source and page numbers) were missed off. Example 3 Mary has written the following on a scrap of paper: “Swiss launch law on genetically modified food.” Discussion Example 1 We think that these must be some notes that Mary has made about one of the sources she's looked at – there's even a good quote, flagged up as important – but there's no indication of the title of the book or journal article in which she found it. She thinks these might be notes made from one of the books she found when she made a special trip to the university library. The notes look really useful. She thinks the book could have been by Smith, but she can't quite remember the title. Safari: Section 6: Organising information Copyright © 2014 The Open University Page 6 of 30 Example 2 We think this looks like a photocopy of a journal article, but it isn't a very good one because the photocopier has cut the name of the journal and the article title off the top. Mary remembers being in a bit of a hurry when she made this copy, and didn't think to check that it had worked properly before heading off from the library. Example 3 We think this is part of a reference – it could be a reference to a book or a journal article, there isn't really any clue, and it could be the title of a chapter or journal article, or a quote. Mary can't remember why it was so important. Activity: Incomplete sources Think about all these incomplete sources and the problems is Mary likely to run into if she wants to use them in her assignment. What should she have done differently? Make a note of your thoughts and then go to the next page to see our comments. Safari: Section 6: Organising information Copyright © 2014 The Open University Page 7 of 30 Discussion The table below provides some suggestions. Problem How you can avoid this problem Mary has incomplete references, so she Make a note of all relevant details e.g. will be unable to quote from these in her author, title and date when you are assignment, or add them to her reference reviewing resources so that you can list. acknowledge your sources appropriately in your own work. This will also help you to find other works by the same author. She hasn’t got sufficient information to be Make a note of when and where you got able to track down where she originally the information from, e.g. local library. found them e.g. from which book, That way you can track back your steps if database etc. you need more details later. Her photocopy is incomplete; bits have When copying, check that you haven’t been cut off the copy. cut off parts of the page, e.g. chapter title, pages numbers etc. Also make sure that the full reference is written on it somewhere even if you have to do this by hand at the time you find it. Table 1: Ways to avoid incomplete sources Safari: Section 6: Organising information Copyright © 2014 The Open University Page 8 of 30 Some ‘golden rules’ You need to remember to record the following information. WHAT you find – journal article/book chapter etc. WHEN you find it – date WHERE you find it – place: publication title (e.g. Journal of Animal Research) as well as physical location (e.g. University library) WHO created it in the first place (author, editor etc.)? Like Mary, you will probably be gathering information from a wide variety of sources. You will need to keep track of what you have got, where you found it, and what it was about in order that you can incorporate it into your work. However, doing this isn't just about physically organising the bits of paper you gather, it's about organising yourself too. This might mean planning ahead to ensure you have the right information at the right time. For example you may need to apply some time in advance for a book via interlibrary loan (for a book that isn't in your local library), in order to make sure that you get hold of it in time for when you are going to need it. Keeping track of what you've ordered and when, and what you still might need to get hold of is tedious but essential. Systematically keeping track of what you've got or what you've had, and recording information about your information, will ensure that you don't have to retrace your steps, can cite references accurately, and provide an accurate bibliography at the end of your project. Being organised in the way you approach your information is ultimately going to save you the one thing that you may not have a great deal of as you get to the point of completing your assignment – TIME! Safari: Section 6: Organising information Copyright © 2014 The Open University Page 9 of 30 Topic 3: Ways to organise In order to investigate ways of organising information we asked some of our OU friends and colleagues about the methods they use. All of them are doing modules that require them to write quite lengthy TMAs or projects but they all have different ways of organising the information that they need to complete these assignments. Sue “I keep photocopies of what I've read in a box file. I used to keep a separate list on my word processor of everything that was in the file but it was too much effort to keep it up to date. I find it just as easy to make sure that the reference is written on the top of my notes, and the notes are clipped to the photocopy, if I made one. I did try storing the articles in alphabetical order by who'd written them, but that made it more difficult to find things again – I tend to think in terms of topics, rather than who wrote what, so the articles tend to be filed alongside other articles on the same subject.” Brian “I keep all my lecture notes and articles in binders, with file dividers, according to what topic they're on. That way everything is in the right place for when I come to revise for the exams or write the assignments.” Safari: Section 6: Organising information Copyright © 2014 The Open University Page 10 of 30 Sandra “I put web pages, ejournals and online stuff into my social bookmarks. I use delicious as it's quite simple to use, and I can access it from any PC connected to the internet. I like the social aspect of seeing who else has tagged sites I use, as it can lead to me to find new stuff for my studies.” Matthew “I use RefWorks to organise all my references. It’s really useful because some of the key databases in my subject allow me to export records straight in RefWorks, and it works with Google Scholar too. This saves me having to manually type things in. I use it to create my bibliographies automatically.” We can't tell you which system to use – everybody's preferences will be different, particularly when it comes to deciding between paper and computerised systems. However, we think that paper-based filing systems are fine for most undergraduate work. If you are comfortable with computers and your work is likely to continue beyond a single assignment, to extended essay or even Masters Level, it may be worth looking into computerised solutions. Safari: Section 6: Organising information Copyright © 2014 The Open University Page 11 of 30 Topic 4: Social bookmarks Whichever internet browser you use you will probably already have discovered the ‘favourites’ or ‘bookmarks’ features and saved some of you favourite sites. This enables you to return to them easily at a later time. However, have you organised them into folders? If you’ve only got a few bookmarks it's not really necessary to do this, but once you have more than a dozen or so then you might like to try organising them into folders according to topics. The following instructions refer to versions of browsers that were current at the time of writing (December 2014). Setting up folders in Internet Explorer 8 Select Favorites (US spelling). Select Organise Favorites from dropdown menu. Select New Folder at the bottom of the box, to create your folder You can now drag your bookmarks into the correct folders. Setting up folders in Mozilla Firefox 31.0 Select the Show your bookmarks icon to the right of the URL and search bars. (Scroll your cursor over the symbols to identify the correct icon). Select Show all bookmarks. Select the Unsorted Bookmarks in the left hand column. To create a new folder, select Organise at the top of the box, and then New folder. You can now drag your bookmarks into the correct folders. Safari: Section 6: Organising information Copyright © 2014 The Open University Page 12 of 30 The downside of these kinds of’ Favorites’ or ‘Bookmarks’ is that they are based on your own PC so if you use more than one machine for your studies or work then you have to save copies on each machine you use. This is where online social bookmarking tools can be really useful, as they allow you to save your favourites to a website which you can then access from any PC connected to the Internet. You can also add keyword tags to sites you save; this enables you to group together items on the same subject. With the bookmarking feature in your browser you put one site in one folder, whereas when using social bookmarks and tagging, you can assign many different tags to the same site. In this way, when you search through your tags, that same site can appear as a resource within as many subject groups as are relevant. Scenario Our Science post-graduate student, Mary, does her studying at home, at work and in her local library. She’s saved sites of interest onto her ‘Favorites’ on her home PC, but this means that when she’s studying at work she doesn’t have access to these resources. A friend has recommended that she try out Delicious, a social bookmarking site. She can set up an account, import all her favourites into Delicious and tag them and then she will be able to access them from anywhere. If she makes her sites public, she will also be able to share them with her friends and her study group by giving them a link to her page. Safari: Section 6: Organising information Copyright © 2014 The Open University Page 13 of 30 Topic 5: Citing references When you are writing an assignment, you will often find that you need to refer to the work of other people in order to support your ideas and illustrate the arguments you are putting forward. Acknowledging the work of others in your writing is all part of the process of communicating your own work to other people interested in what you have written. This process of acknowledgement is known as ‘citing’. Activity: Why cite? Why do you think it is important to cite references in your work? Make a note of your thoughts and then read the discussion below. Discussion Here are some of the things we thought of: You will be recognising the intellectual input someone else has made to your work – passing off someone else's work as your own is called plagiarism. It shows that the points you are making in your work are supported by other people – your arguments are stronger if you can back up what you say with evidence. It enables other people reading your work to find the things you have referred to quickly and easily. It shows your tutor not only what you have been reading but also where you have been reading around the subject. Safari: Section 6: Organising information Copyright © 2014 The Open University Page 14 of 30 When do I need to cite? Commonly known facts and dates (e.g. that World War II ended in 1945) do not need crediting in your work. Everything else, such as quotations, statistics, or any ideas or opinions that aren't your own, should always be cited in your work. The extracts below are taken from students’ essays and illustrate the kinds of things you should avoid. Extract 1 “Although instructors may be lured by the freshness of full motion videos or two-way conferencing, the type of instructional delivery depends primarily on four aspects.” It isn't obvious at first glance why this should be avoided. But if I had simply copied this quotation and included it in my work without acknowledging that it was the work of someone else, I would have been guilty of plagiarism It may seem very tempting to 'borrow' ideas and words from somebody else's work, especially if you aren't all that familiar with the subject area. But if you don't use your own words, your writing won't 'read' all that well - people's writing styles differ, after all. Notice how different the quotation above is from the rest of the writing on the page you are reading now. Also, if you don't work towards expressing ideas in your own words, it is unlikely that you'll take them in. (Quote from Dewal, Nancy (2000). 'Information literacy at a distance: instructional design issues', Journal of Academic Librarianship, vol. 26, no.1.) Safari: Section 6: Organising information Copyright © 2014 The Open University Page 15 of 30 Extract 2 “It has been shown that dogs are more intelligent than cats …” What research? Whose research? Extract 3 “We know from the research that 95% of statistics are made up.” How do we know? Who proved this? If you have read academic research papers, journal articles or books, or even the more serious articles in broadsheet newspapers, you will probably have come across citations. There are a number of ways in which this is done and some references do not even include direct text quotations. Below are some examples with explanations of what they are. Example 1 “The best advice is to experiment with a range of different search tools, and settle on the two or three that provide you with the best results (Parker, 1999).” This is an example of citing somebody else's idea or opinion, you are paraphrasing, not referring to the author in the text nor directly quoting from their work but if you didn't acknowledge their idea, it would look like it was your own. Safari: Section 6: Organising information Copyright © 2014 The Open University Page 16 of 30 Example 2 “However, Tim Berners-Lee, widely acknowledged as the inventor of the World Wide Web ...” As this is a commonly known fact, you wouldn't need to cite it in your work. Example 3 “As Gash (2000) states, browsing the Internet can be enjoyable. Sometimes information can be found by accident, but this can take time and the serious searcher might find this frustrating, particularly if they are not familiar with how search engines work.” This is an example of acknowledging someone else's opinion directly. Example 4 “This is further illustrated by Spender: "As there are no teachers, librarians or sages to help you make your way around on the information superhighway, the most common complaint is that it is too hard to find what you need." (Spender, 1995, page xvii)” Quotations from someone else's work should always be acknowledged. Safari: Section 6: Organising information Copyright © 2014 The Open University Page 17 of 30 A final comment about citations Identifying an original author in your text is sometimes not enough to fully acknowledge someone else's research, especially for academic work. Think back to the snippets on the previous pages – from the information given about them in the text would you be able to locate the sources we have referred to in your library? Probably not. Directing your readers to the sources you have used to produce your work is all part of the research process. Citing references in the body of your work should go hand in hand with providing a bibliography – a list of those same references – at the end of your piece of work. So, make sure to provide a citation next to the opinion or idea that you have used within your written work, this will signpost any reader to look for a full reference in the list of references at the end. Safari: Section 6: Organising information Copyright © 2014 The Open University Page 18 of 30 Topic 6: Bibliographies At the end of your piece of work, you should provide a list of all the things you have referred to in your work. These might be arranged in alphabetical order by author, or in the order they are mentioned in your work. The convention at the Open University is that you should call this list ‘references’. ‘Bibliography’, quite literally means ‘list of books’ – it enables you to find a book (or journal article) in your own library, regardless of where the person who wrote the bibliography got their original copy from. Sometimes there may be sources you have consulted as background reading, but have not mentioned in your work – you might like to put these in a separate list entirely, after your list of references, calling it ‘bibliography’. The rest of this topic examines the type of information that you need to include in a bibliography. Activity: Finding a book Imagine you are going into a library or bookshop to look for a book. What information do you think you might need in order to find it quickly? Make a note of your thoughts and then read the discussion on the next page. Safari: Section 6: Organising information Copyright © 2014 The Open University Page 19 of 30 Discussion You would need the following information: the book's title who wrote the book who published the book the book's ISBN number the year the book was published the place the book was published. If the library or bookshop has a searchable database of books, two of these in combination – for example, author and year, publisher and title – will enable you to track down an item eventually. However, the key to a good bibliography is supplying all the information, so that there are no gaps, and the detective work for your readers is minimised. Remember that what you are trying to do is to give your readers the opportunity to find and read the same things you have read, so you need to be as precise as possible. Activity: Finding a journal article and referencing a web page Now we want you to consider two more types of information: journal articles and web pages. For each of the questions below make a note of your thoughts, and then read the discussion below. Think about a journal article. What information would you need to give somebody in order for them to find it? Providing references to information from the World Wide Web is especially problematic. Why do you think this is? Safari: Section 6: Organising information Copyright © 2014 The Open University Page 20 of 30 Discussion We think you’d need the following information to find a journal article: author title journal title volume number page number issue year of publication. Providing information on web pages can be problematic because: much information is transient – there one day and gone the next it isn't always evident who the author/publisher is web addresses change the information given might quickly go out of date. Referencing web–based materials is particularly challenging because of these problems and because, more and more, important and relevant information is found on the web. We shall look at how to reference these sources next. Safari: Section 6: Organising information Copyright © 2014 The Open University Page 21 of 30 Referencing the web As we have seen, you are likely to come across several problems when referencing information from the web. It is increasingly being recognised as a valid information source – sometimes the sole source of certain information – but pages on the web tend to change frequently. So, how can you describe the exact source you have found? One way to tackle the problem is to add to the reference the date on which you visited the site to gather the information you used. This won't ensure that your readers will get the same information if they look at the site another day, but it will make your use of the source more valid – as if to say, ‘on this date the site was there and the information I got from it was like this’. So, a reference to something you have found on the web might look like this: Lancaster University Computing Department, Research Schemes: Cooperative & interactive systems [online], Lancaster University Computing Department. Available from: http://www.comp.lancs.ac.uk/research/advinteractivesystems.html [Accessed January 13 2011]. Of course, there are other kinds of documents on the web too. The OU Harvard Guide (OU login required) provides advice on referencing all sorts of materials. Safari: Section 6: Organising information Copyright © 2014 The Open University Page 22 of 30 How should my references look? No matter how diligent you are about citing every source you consult, if your references aren't presented in a systematic, consistent way, the people reading your work are going to become frustrated when trying to track down the sources you have used. The trick is to adopt a suitable citation style, for the citations in the text and for the list at the end, and use it throughout your piece of work. There is no one ‘right’ style – many publishers and organisations have come up with rules which dictate how the references in the text and in the list at the end are presented. Activity Over the next two pages you will find two versions of the same piece of text. Look carefully at them and make a note of: what is different what is the same? Then read the discussion which follows after the two versions. Safari: Section 6: Organising information Copyright © 2014 The Open University Page 23 of 30 Version 1: MLA As Gash states, browsing the Internet can be fun. Sometimes information can be found by accident, but this can take time, and the serious searcher might find this frustrating, particularly if they are not familiar with how search engines work. This is further illustrated by Spender: "As there are no teachers, librarians or sages to help you make your way around on the information superhighway, the most common complaint is that it is too hard to find what you need" (Spender, pxvii). Even when using search engines it can be difficult to find what you need, as recent research has shown that the majority of search engines only return 10 ‘hits’ within the first 20 on the results list that might be relevant to the searcher (Gordon and Pathak). The best advice is to experiment with a range of different search tools, and settle on the two or three that provide you with the best results (Parker). References Gash, Sarah.

Table 2: Examples comparisons Despite all these differences, the information that builds up each reference is the same, and would enable you to track down that source for yourself. The choice of citation style you use is often dictated by WHO you are writing FOR – this might be your tutor, the journal your article might be published in, or your organisation. It also depends on your topic and how you would like your bibliography to look. If your college or university does not specify which style you must use then the most important thing is to choose a particular style and use it consistently and uniformly, so that your readers get clear information. If you would like to delve into further examples of citing references, there is a guide on the Library's web pages. Safari: Section 6: Organising information Copyright © 2014 The Open University Page 26 of 30 Tool to help you You will find that creating bibliographies can be quite a lengthy process. Bibliographic software packages can help do this as they will create your list of references, and the in-text citations, for you automatically. If you are using a word processor, check to see whether it offers a referencing function (called ‘Endnotes’ in Microsoft Word). There are a number of freely available web-based bibliography and database management tools. These let you create your own personal database by importing references from text files or online databases. CiteULike – a free social bookmarking service to help academics to share, store, and organise the academic papers they are reading. It specialises in academic papers, and provides specific tools for that purpose. Mendeley – free desktop and web-based tool. Features include automatic extraction of information from PDF documents; the facility for annotation and searching across all content, and the option to share publicly or privately for collaboration. Zotero – free bibliographic software. Features include automatic capture of information from websites, formatted citation export and integration with Microsoft Word. If you are comfortable with computers and your work is likely to continue beyond a single assignment, to extended essay or even to Masters Level, then we strongly recommend that you investigate one of the free tools listed above. Safari: Section 6: Organising information Copyright © 2014 The Open University Page 27 of 30 Activity: Writing a reference list You may need to refer to the OU Harvard guide to citing references for this activity (OU login required). Imagine you are putting together a list of references to go at the end of an assignment. Using a pen and paper or your word processor, write down how the following references should look when formatted for the reference list. a) A book written by Andrew Northedge, published in Milton Keynes by The Open University in 1990. It's called The Good Study Guide. b) A journal article called Getting to Know the Invisible Web by C. Brian Smith, which appeared in volume 126, issue 12, of the Summer 2001 Supplement of the Library Journal, pages 16 to 19. c) The Learner's Guide, a web page produced by the Open University, written by the Learner's Guide team, which I looked at on 23rd June 2001.
