For participants who would like more information about the Internet the BHP Billiton skills.net course ‘Getting Started’ is recommended. It is available on State Library’s website at www.slq.qld.gov.au i) The course The aim of this course is to assist library staff to link their community with quality information that meets their needs. To achieve this aim we will look at the changing information environment, issues impacting on the ability to provide clients with the best possible information available and strategies to keep up to date. ii) The objectives for this course are that at the conclusion of this training all participants will be: 2 • aware of issues which can impact on the ability to meet the information needs of your community • able to identify the most appropriate method/resource to find information for clients • aware of the changing information environment and how to keep up to date professionally OPAL Training Project State Library of Queensland 4 February 2008 1. ISSUES THAT CAN IMPACT ON THE ABILITY TO LINK CLIENTS WITH RELEVANT INFORMATION Knowledge of the information environment • Amount of information available - terms such as the “information explosion” and “information age” indicate that we have at our disposal (mostly thanks to the Internet) large quantities of information. How do we navigate this quantity of information to find the best to suit our needs? • Kinds/formats – as well as our traditional print resources, we now have access to online resources in a variety of formats eg PDF (portable document format). We have access to web resources via search engines, subject directories, meta-search engines, online databases. Knowledge of these tools enhances our information seeking process. • Availability – we can now access information 24 x 7, no longer being limited to the library and library opening hours. People can access information from home or anywhere they have Internet access. Changes in society • Workplaces/ workplace skills are changing and are affecting people’s needs for information and the skills needed to access information. There are fewer unskilled jobs available and very few jobs that require no knowledge of information technology. Increasingly people need IT skills to survive and the nature of fewer unskilled jobs means a lifetime of learning to remain employable. • Personalization – there is an expectation now that everything can be tailored to individual needs. This has flowed onto the provision of information eg My Yahoo!, MyEBSCOhost, My e-bay • Knowledge economy – information in our society is now a commodity. Those people who can access information effectively are at an advantage. Library professionals play a key role in building the knowledge economy in our communities. • Client expectations – client’s information expectations have risen. Due to many factors, including misconceptions that anything can be found on the Internet, clients do not expect to walk into a library and come away with no information. What can we provide for our clients if we cannot find the exact answer? OPAL Training Project State Library of Queensland 4 February 2008 3 Knowledge of your community • Information literacy – providing information is not enough – access and information literacy skills are needed. How skilled is your community? • What are they using the Internet for? For example: finding information, online banking, helping children with assignments. Knowledge of your community will inform the way you promote information for them. Awareness of what exists • How do you find out about new information? Do you belong to a professional group who updates you? Are you on mailing lists? Do you have good knowledge management practices in your area? Your own knowledge – is it dated? • Your ability to stay up-to-date with the latest trends and technology in information delivery directly impacts on the end product you provide for your clients. Your ability to evaluate information on the Internet • Information on the Internet ranges from high quality, informative professional resources to anything and everything an individual can post. What are the things you need to be aware of to assess the quality of a website? Reference Interview – are you making the most of the time? • 4 Do you know exactly what your client is seeking? Often your client will ask you for something at the information desk when really they want something quite different. Finding out exactly what your client wants impacts on the appropriateness of information they will receive. OPAL Training Project State Library of Queensland 4 February 2008 Your reference desk and computer set-up • Can you quickly locate information? Have you got a second window open to access subject directories or your favourite search engine? • Does your circulation staff know when to refer queries to professional staff? Knowledge of latest software etc so that clients can use sites • To be able to use sites to their full potential software may need to be loaded on your PC eg QuickTime, adobe, shockwave. Is this an issue for security on your computers? How easy is it to get permission to have this software installed? Do you really have a good understanding of how your computers are set up or is this knowledge in the IT department of your organization? Barriers – policies/charges • Are your photocopying/ Internet access charges prohibitive to finding information? How do charges and policies cause barriers to providing the best information for your clients needs? OPAL Training Project State Library of Queensland 4 February 2008 5 2. SEARCH OPTIONS 2.1 SUBJECT DIRECTORIES Defining Subject Directories • Subject directories are organized by humans. Web sites are manually selected based on predetermined criteria, therefore there is a high degree of accuracy and quality in the results. • Subject directories organize chosen web sites hierarchically into lists of subjects. These general subjects are then broken down into subcategories. • There are commercial (www.Yahoo.com) and non-commercial (academic and professional) (netlinks.slq.qld.gov.au) subject directories. • Commercial directories or portals are aimed at the general community eg. Looksmart. Website developers often pay a fee for inclusion in such a directory. • Academic and professional directories are compiled by experts and usually contain links to relevant and useful information. • Try to find out the criteria adopted by subject directory developers for web site inclusion. If the web site includes information about criteria and selectors, the information found may be more trustworthy than web sites included in directories where this information is not made freely available to users. Netlinks is a good example of criteria for selection. http://netlinks.slq.qld.gov.au/about.htm Advantages • Good for browsing. Useful when you want to see what range of information is available on a topic – akin to reading the content pages of a book. • Compiled by human editors so results are quite accurate. • Fewer hits than when using a search tool but results are likely to be more accurate. Disadvantages • Be wary about the reason for the inclusion of certain web sites in commercial subject directories. • Compiled by human editors who may have different ideas about which subject category a topic relates to. 6 OPAL Training Project State Library of Queensland 4 February 2008 When to use a subject directory • When you want an overview of the categories of information available on a subject eg. Cooking, dogs, planets. • When you want to retrieve a list of sites relevant to your topic, rather than numerous individual pages contained within those sites. • When you are trying to decide on a topic eg. One of the planets in the solar system. How do I use them? • Simply choose from the list of subjects the one that best suits your search. • Then work through the various lists of sub-categories until you are presented with a list of relevant web sites. For Example – If you were searching for web sites about the planet Mars, you would select the Subject Area “Science” and then choose the pertinent sub-categories. Artificial life Choose from sub-categories Astronomy Astronomers Chemistry Eclipses Ecology Galaxies Medicine Planetaria Physics Solar System Telescopes Choose from sub-categories Asteroids Planets Sun Choose from sub-categories Earth Mars Jupiter OPAL Training Project State Library of Queensland 4 February 2008 7 Examples of Subject Directories: Netlinks http://netlinks.slq.qld.gov.au • A subject directory created and maintained by State Library of Queensland • More information can be found on p. 30 Yahoo! http://dir.yahoo.com • Is the world’s oldest directory – launched in 1994 • Organises web pages in the database into 14 major topics which are further divided into subcategories • Sites pay a fee for inclusion in the Yahoo Directory’s commercial listings, though they must meet editor approval before being accepted • Yahoo! also provides a site especially designed for children called Yahooligans at http://kids.yahoo.com • Sponsored links more prominent • One component of a suite of services offered by Yahoo! including a search engine discussed on p. 17 • www.yahoo.com provides access to Yahoo! services through their portal Web Site Directory - Sites organized by subject 8 Suggest your site Business & Economy Regional B2B, Finance, Shopping, Jobs...

These are designed to help users (eg students, lecturers and researchers) improve their Internet information literacy and IT skills. These tutorials are self paced and provide quizzes and interactive exercises to lighten the learning experience. • full listing of the tutorials available can be found at: www.vts.intute.ac.uk Examples of International Gateways: SOSIG (Social Science Information Gateway) http://www.rdn.ac.uk/www.sosig.ac.uk/ www.sosig.ac.uk • Is a freely available Internet service which aims to provide a trusted source of selected, high quality Internet information for students, academics, researchers and practitioners in the social science sciences, business and law • The SOSIG Internet Catalogue is an online database of high quality Internet resources. The catalogue is browsable or searchable by subject area and offers users the chance to read descriptions of resources available over the Internet and to access those resources directly. The Catalogue points to thousands of resources that have been selected and described by a librarian or academic. • The Social Science Search Engine is a database of over 50,000 Social Science Web pages. The web pages included in this collection have been collected by software called a 'harvester' (similar mechanisms may be referred to as 'robots' or 'Web crawlers'). • SOSIG is a service of the Resource Discovery Network. The RDN is a collaboration of over seventy educational and research organisations, including the Natural History Museum and the British Library. 12 OPAL Training Project State Library of Queensland 4 February 2008 GEsource (Geography and Environment Gateway) http://www.rdn.ac.uk/www.gesource.ac.uk/www.gesource.ac.uk/home.htm l • Provides access to high quality Internet resources for students, researchers and practitioners in geography and the environment through five distinct subject gateways: Environment, General Geography, Human Geography, Physical Geography, and Techniques and Approaches.

Artifact is a free service. However some resources Artifact describes require a subscription and/or id and password in accordance with the Publisher or Content Provider’s subscription policy. OPAL Training Project State Library of Queensland 4 February 2008 13 2.3 SEARCH ENGINES Defining Search Engines • Search engines consist of three parts: 1. Robots, bots or spiders that collect links 2. A database where the information is stored; and 3. Technology which allows users to search the index and return the results • Robots crawl through the Internet and locate web pages to index for inclusion in the database • Robots choose which words to index based on their location on the page and how frequently they are repeated throughout the document (unless keywords are specified using metadata tags). Some robots will index every word in the text except those listed on the stop list such as “and”, “the”, and “a”. Some databases use another process called stemming that removes suffixes (-s, -es, -ed) and may also remove (-able, -ability, -ness) from keywords when creating the indexes. • The searcher then enters a search query into the front-end search facility, usually in the form of a search box • If the search is successful, a list of results is presented, ranked in order of their relevance to the search terms entered. Ranking systems used by search engines vary. Ranking is based on an algorithm or a set of rules. Most use “fuzzy and” combined with factors such as how often your terms occur in documents and whether in the title or how near the top of the text. (“Fuzzy and” means that documents which contain all of the search terms are displayed first followed by documents that contain only some of the search terms). • Google determines relevance by analyzing how many other web sites link to each web page and the importance of those pages (eg. A government site would be rated as more highly than a porn site). It also ranks sites according to how frequently they have been accessed by previous searchers. • No one engine searches the entire web • Highest ranking search results can vary much between search engines. Try the research tools, http://ranking.thumbshots.com and www.jux2.com to compare the ranking of search results from different search engines. • No two search engines are exactly alike • Using a search engine is like using the index of a book 14 OPAL Training Project State Library of Queensland 4 February 2008 Advantages • Very easy to search for topics, simply type in a search word or phrase • The ranking system allows you to view the most relevant search results quickly Disadvantages • As there is no human intervention, the accuracy of some of the pages found can be dubious. Some of the pages displayed may have no relevance to the initial search query. • Web sites that include different terminology than the terms entered in the search will not be found When to use Search Engines • When you are undertaking a specific search • When you are searching for an obscure topic • When you want to take advantage of the latest retrieval technologies Examples of General Search Engines: All the web www.alltheweb.com • Uses Yahoo!’s index and is powered by Yahoo! • Focuses on web search but also searches news, video, pictures, mp3 files, ftp files audio • Offers search customization OPAL Training Project State Library of Queensland 4 February 2008 15 Google www.google.com • Has the largest database of indexed web pages – in October 2004 announced they had indexed over 8 billion sites • It takes 4-6 weeks for new pages to be indexed and included in the database • Type in your search terms/phrases, click on “I’m feeling lucky” to go straight to the first site in the listing • "Google Answers" - the searcher registers their question and pays a fee for the answer • Use the cached link to view a previous version of the page • Offers excellent spell checking facility • Find definitions easily from the search box • Perform calculations using the search box • Google Alerts email the latest search results on a particular topic to you as they are indexed • Google desktop allows you to search your own computer for emails, files, web history and chats • 60 interface languages • Offers search customization • Test program, Google Print shows links to books whenever a book contains content that matches your search terms (For more information go to www.print.google.com ) • Check out additional functions under “more” Soople www.soople.com 16 • Written for the creator’s mother to make it easier to use Google • Advanced search functions of Google organised and meant for those who are not yet familiar with all of the functions and required syntaxes OPAL Training Project State Library of Queensland 4 February 2008 Yahoo! Search www.search.yahoo.com • Since February 2004 Yahoo! has used it’s own technology to provide crawler based listings (from 2002 to 2004 it relied on Google’s results) • Searches the web exclusively, does not search directory • My Yahoo! Search allows personalisation through sign in feature and saving results, catagorising results, blocking sites and searching within My Web • Is the closest competitor to Google in the US – in July 2004 the percentage of searches measured in the US were 31.5% by Yahoo! compared to 41.6% by Google (Nielsen//Net ratings survey) Hotbot www.hotbot.com • Launched in May 1996 by Wired Digital then purchased by Lycos in 1998 • Developed a strong following in the early years for quality and comprehensiveness • Search features suffered in 1999/2000 when Lycos focused on developing portal content • Lycos refocused on search capabilities in 2001 • Also provides access to Google and Ask Jeeves but it is not a meta search engine in that it cannot blend the results of these search engines together OPAL Training Project State Library of Queensland 4 February 2008 17 Ask.Com www.ask.com Initially gained fame in 1998 and 1999 as the “natural language” search engine that let you search by asking questions and responding with what seemed to be the right answer • Hasn’t always relied on technology for results. At one point had up to 100 editors who monitored search logs and went onto the web to locate the best sites to match the most popular queries • Today uses crawler based technology and results come from Teoma • See also Askforkids – http://www.askforkids.com Teoma www.teoma.com • Teoma first appeared in May 2000. It was purchased by Ask Jeeves in September 2001 • Smaller index to the web than Google and Yahoo! however has won praise for it’s relevancy since it appeared in 2000 • “Refine” feature offers suggestions to narrow your search • “Resources” point users to pages created by experts and enthusiasts that serve as link collection on your search topic Additional general search engines are listed at • Search Engine Colossus www.searchenginecolossus.com Provides links to search engines from around the world • Search Engine Watch http://searchenginewatch.com/links Search engines are listed in various categories. • Search Engine Showdown www.searchengineshowdown.com Provides information on search engines including reviews and a features chart 18 OPAL Training Project State Library of Queensland 4 February 2008 Examples of Australian search engines Web Wombat www.webwombat.com.au • Operating since 1994 and was one of the world’s first search engines • Was the world’s first regional search engine • Claims to be the world’s first search engine to add non-search-related content to it’s website, making it the world’s first web portal • Uses search technology developed by an Australian • Has indexed more than 11 million Australian web pages Anzwers www.anzwers.com.au • Is powered by Yahoo! so few differences between using it and www.yahoo.com.au Other ways of finding Australian content using search engines Using search box settings • To search for Australian content using Google, go to www.google.com.au and select: pages from Australia • To search for Australian content using Yahoo! go to www.yahoo.com.au and select: AU only Using domain limiters in advanced search screens • Many search engines and meta search engines have the ability to limit searches by domain • This feature is usually found in the advanced search screen OPAL Training Project State Library of Queensland 4 February 2008 19 2.4 META SEARCH TOOLS Defining Meta Search Tools • Metasearch tools allow you to conduct a search at a site which transmits your search to a number of individual search engines. Essentially, you are searching the indexes of a number of search engines and the entries of some directories. • There are many search engines and new ones emerging all the time. Meta-search engines are getting better and offering some good features. Advantages • Able to search numerous individual search tools at once • Use of new technologies such as clustering allow for results to be displayed in more meaningful ways Disadvantages • Meta search tools can be prone to timing out due to the size of the search • The meta search engine may not support all of the search features offered by individual search tools • Meta search tools are only as good as the search engines they search When to use Meta Search Tools • If you have already conducted an unsuccessful search using one or two search engines select a meta search tool that searches other directories and search engines • Use meta search tools when you wish to conduct a fast overview of the information available on a topic • Meta search tools are also useful when you are searching for an obscure topic because you cover more than one search tool Examples of Meta Search Tools: SurfWax www.surfwax.com • Searches against major search engines • Can customise in My Preferences after signing up at a free or higher level • Offers a variety of features to help you dig deep into your results • Searches results can be saved in Info Cubby for future use 20 OPAL Training Project State Library of Queensland 4 February 2008 Clusty http://clusty.com • Winner of the Best Meta Search Engine award from Search Engine Watch in 2002 • Core technology is document clustering or automatically organising documents into groups or folders when the search is being processed and without human intervention. Clusty uses the titles, URLs and short descriptions to organise the documents. • Able to preview pages in search results page Dogpile http://dogpile.com • Winner of the Best Meta Search Engine award from Search Engine Watch in 2003 • Searches Google, Yahoo!, Ask.com, About, MSN and more • Offers alternate, related search topics • Records recent searches Turbo10 http://turbo10.com • Provides access to searching over 2000 search engines/databases • Allows you to create your own collection of search engines/databases to search the web (maximum of 10 search engines per collection) • You can create up to 10 collections • Collections are emailed so that you can access these from any PC • Searches the deep or invisible web OPAL Training Project State Library of Queensland 4 February 2008 21 • Clusters results, showing the top 10 clusters for each search KartOO http://kartoo.com • Compiles results and represents them in a series of interactive maps • The search screen can be changed to a variety of different languages • Found sites are represented on the map with more or less pages, depending on their relevancy Ixquick http://ixquick.com • Searchers can choose to search the web, news, mp3 or picture sites • Ixquick is able to translate your search query containing boolean or wildcards into syntax that can be searched by the search engines that can handle complex queries • Results are allocated a star for every match in the top 10 results of each search engine. The results with the highest number of stars are listed at the top of the list. Metacrawler http://metacrawler.com • One of the oldest meta search engines, developed in 1994 and released on the Internet in June 1995 • Use www.metaspy.com to find out what other searchers are looking for • Searches Google, Yahoo!, Ask Jeeves, About and many more 22 OPAL Training Project State Library of Queensland 4 February 2008 2.5 THE DEEP WEB Defining the Deep Web • Also called the Invisible Web • It is the part of the World Wide Web that is not indexed by search engines. Search robots or spiders are unable to carry out the indexing process on many of the Deep Web sites because of their formatting or because there are no links to the site. • Objects that make up the Deep Web are either stored in databases or produced in non-HTML formats. This used to include formats such as PDF files, images and sound. Objects still part of the Deep Web include formats such as macromedia flash. Because of the highly competitive environment of search companies and the advantages of being able to index more of the Deep Web, what search engines are able to locate and index is continuously changing and developing. • An estimated 500 times larger that the known “surface” World Wide Web • It is also estimated to be the largest growing category of new information on the Internet. It has been reported recently that the Deep Web is made up of “550 billion web pages, while the surface web is made up of a mere 1.2 billion” (Gliddon, 2001:64). • The key to locating information on the Deep Web is to be aware of the gateways to these resources. A number of useful web sites for locating information held on the Deep Web are listed on the following page. Examples of Deep Web search tools: CompletePlanet www.completeplanet.com • Accesses search engines and searchable databases • Queries can be entered in natural language or browse the directory • Supports full Boolean capabilities OPAL Training Project State Library of Queensland 4 February 2008 23 Internet Wayback Machine www.archive.org/index.html • Enter the URL for a web site in the search box to locate an archived copy of a web site if it is available • Provides access to specialised collections eg. archival movies 24 OPAL Training Project State Library of Queensland 4 February 2008 2.6 DATABASES • Commercial databases are collections of information presented electronically. Databases range from library catalogues and white-pages directories to several billion records contained in the larger news databases. • The commercial information environment began in the 1960’s. It has developed into a valuable but expensive research resource. • Databases are arranged into either full-text or bibliographic information (or a combination of both) • Databases have their own particular idiosyncrasies and require individualized searching techniques Full text databases • Access to databases has shifted to provide online access via the Internet • Often with Internet access, a site will offer free searching but will charge for the articles. In the main, full text retrieval is a commercial enterprise. • Access to full text information is provided to the public by libraries that take out subscriptions to these services • State Library provides access to several online databases for all Queensland public library members. These databases provide access to full text newspaper articles, magazines and reference books. • Information about the databases that State Library subscribe to and that are available Queensland wide to public library members begins on page 34 of the workbook OPAL Training Project State Library of Queensland 4 February 2008 25
