Library resources for year 3 chemists

  1. 1. Literature Searching Chemistry Lynne Meehan Room 314, UCL Science Library Email : l.meehan@ucl.ac.uk ☎: 020 7679 2634 Literature searching Carrying out literature searches takes time. Developing your information skills will help you to produce literature reviews faster and to a higher standard. • It is possible to “speed up” the searching process by using consistent, structured approach as well as by making use of alerting services and “saved searches” • You can improve your standard of your review by including material from a broad range of information sources, including those with which you are less familiar.

Tracking progress It's a good idea to keep a list of which resources you plan to use, where you're going to look for information and what you're going to look for. Keep some sort of diary, journal or log book to track the progress of your thinking and learning. In the diary you may want to record details of: • Places you have looked or need to look • Useful search terms • Contacts who can help you with one aspect or another of your work Decisions you are making as you go along e.g. when particular bits of information have caused you to shift your thinking • Things that didn't work out e.g. search terms that were too broad 1

  3. 3. Topic- Overview and Define Overview of topic Before you begin, get an overview of the topic you are researching. Especially if you are not familiar with the topic. Good places to get an overview are:- Encyclopedias e.g. Encyclopedia Britannica, Wikipedia Subject dictionaries e.g. A dictionary of Chemistry, edited by John Daintith Subject websites e.g. www.ucl.ac.uk/library/guides/subjchem.shtml Lecture notes This will also help choose concepts and keywords to describe your topic when searching. Define your topic Go through the following steps :-  Think about the question you want to answer and break it down into its braod areas or concepts. You usually find that your question breaks down into a couple of areas or concepts.  Brainstorm for words and phrases associated with the major areas or concepts.  Remember to include synonyms and alternative spellings and colloquial and scientific/chemical terms -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.  Are there any grographical or date limitations you need to build in to our search? (e.g. are you looking for the worldwide or european perspective? Are you interested in historical or very current materials?. The process may help you decide what you don’t want to investigate as well as what you do – saving you time when deciding what to read and what not to read. Task 1 In groups discuss the topic “Current problems with understanding polar ozone loss” and write down the main concepts and find keywords and synonyms for the concepts. 3

  5. 5. Search Techniques Boolean • If you want an online database or search engine to understand you, you need to speak its language. That's why syntax - the way you put your search terms together - matters. • Since syntax can vary between databases and search engines, you should refer to the help. • For an online tutorial of any of the databases listed here, see section 3 of WISE (Finding information) for online tutorials: go to http://www.moodle.ucl.ac.uk/, log in, click on WISE, and select WISE for Maths and Physical Sciences. Connectors (or 'boolean operators') Connectors determine how multiple search terms are combined in a search. Three common connectors are and, or and not. Sometimes symbols are used instead of words, i.e. + or – Polar regions Polar ozone Ozone layer Polar OR Ozone Polar NOT Ozone Polar AND Ozone . Extra search tips Nesting: The order in which search engines execute your commands is not always obvious. You can use round brackets ( ) to control the search sequence. • Example: the search term ozone and (loss or depletion) will find documents that contain one of the words in brackets -i.e. loss or depletion – but only if they also contain the word ozone. 5
  6. 6. Proximity operators: locate terms that are close to one another. One such proximity operator is w/#, which you can use to find two words that are # number of pages apart. • Example: ozone w/3 depletion will find documents where ozone and depletion occur within three words of one another, in either order. Phrase searching: Some databases will treat two or more words entered into the search box as a phrase, while others require you to place a phrase in double quotation marks “”. • Example: "ozone layer” will only find documents where the whole phrase is present. Truncation: Most databases allow end of word truncation, using one character, such as an asterisk *, to replace the remaining letters. • Example: caus* will find documents containing cause, causes and causative 'Wild cards': Wild cards are characters, such as a question mark, ?, used to replace replace a single letter in the middle of a word. They are used to accommodate spelling variations. • Example: wom?n will find woman and women; organi?ation will retrieve organization and organisation. Searching specific fields: Field searching allows you to designate where to search for a specific term. Sometimes there is a drop-down menu to select the field, at other times a field 'qualifier' is added to the search term, such as Smith:au or Smith in au Web The web is a useful source of information but it is quite unlike library catalogues and databases in that it isn't so neatly organised and varies greatly in quality and usefulness. Below are some ideas to try and improve your web searching. • Google is not the only search engine, try Yahoo www.yahoo.com Exalead, www.exalead.com/search • You can also take advantage of human selectivity, using the websites below Librarians’ Internet Index - www.lii.org Intute – www.intute.ac.uk • Refining your search terms will help. On most web search engines you can use the ‘refine’ or ‘advanced’ search to limit the number of ‘hits’ for any particular search • Think “full text” and be specific e.g. war of 1812 economic causes vs. history • Use academic & professional terms e.g.domestic architecture vs. houses 6
  7. 7. • Limit your search to … Web page title intitle:hybrid allintitle:hybrid mileage Website or domain site:whitehouse.gov “global warming” site:edu “global warming” File type filetype:ppt site:edu “global warming” Definitions define:pixel define:“due diligence” • Remember social bookmarking, youtube, blogs Some useful subject sites to use Scirus – www.scirus.com Sheffield chemdex - http://www.chemdex.org/ Invisible Web - What is the "Invisible Web", a.k.a. the "Deep Web"? The "visible web" is what you can find using general web search engines. It's also what you see in almost all subject directories. The "invisible web" is what you cannot find using these types of tools. - Why isn't everything visible? There are still some hurdles search engine crawlers cannot leap. Here are some examples of material that remains hidden from general search engines: • The Contents of Searchable Databases. • Excluded Pages. • Dynamically generated pages of little value beyond single use. • Pages deliberately excluded by their owners. - How to Find the Invisible Web Use Google and other search engines to locate searchable databases by searching a subject term and the word "database". If the database uses the word database in its own pages, you are likely to find it in Google. The word "database" is also useful in searching a topic in the Google Directory or the Yahoo! directory, because they sometimes use the term to describe searchable databases in their listings. The Wikipedia "Deep Web" article provides a fairly up-to-date summary, with links to other resources. Database's A database is a way of storing, indexing, organising and retrieving information 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. They are a very quick means of accessing thousands of references to academic material. 7
  8. 8. Some databases have a very narrow focus, while others contain information on many topics. Select a database that is appropriate for your topic - see the subject guides http://www.ucl.ac.uk/Library/guides/subjguide.shtml or browse the list of databases http://www.ucl.ac.uk/Library/database/index.shtml A brief list of databases for your subject, including search tips unique to that database, is below Web of Science – Science Citation Index Web of Science is a ‘Citation database’. This means that it contains bibliographic information from journals and also the article's cited reference list (often called its bibliography). It is a multi-disciplinary database, which is in three separate indexes: The Science Citation Index indexes more than 6650 major journals across 164 scientific disciplines from 1945 onwards. Social Sciences Citation Index and the Arts & Humanities Citation Index are also available. Scopus Comprehensive scientific, medical, technical, social science, and arts and humanities database containing references to journal articles, conference proceedings, trade publications, book series and web resources. Indexed from 1823 onwards. Knovel Knovel is an interactive e-book and database package which gives searchable access to the full text of a range of text and reference books. It covers all aspects of engineering and applied science. Reaxys Chemical information system, covering chemical compounds, bibliographic data and chemical reactions. Includes the content of the three CrossFire databases: Beilstein, Gmelin and Patent Chemistry Database, producing a single results set. Web of Science Step by step guide of demo 1. Go to the Web of Science page  Go to UCL library homepage www.ucl.ac.uk/library  Click on Electronic Resources  Click on Databases  Click on W  Click on Web of Science You should now be at the main search screen. You can search by keyword, author, title, publication name and so on. 8
  9. 9. 2. Entering a search For example, our search for papers about “Current problems with understanding polar ozone loss”  Enter search into Web of Science as follows  1st search box polar or arctic or antarctic  2nd search box ozone (loss or depletion)  Change search type to topic for both boxes  Click on help if you want more info on the search rules that Web of Science uses.  Click on search. How many results do you get? 3. Results screen  The default setting is to display 10 results per page in year order with the most recent first  For each result, you can see brief information of title, author and journal details.  There are links to click on to see abstract and full text.  You can mark (check the boxes) the results you find useful to make your own list of resources. Once you have done this you can print, email the selected reference or save them to reference manager 4. Limiting search If you have too many results you may want to reduce them. You can do this by “refining” our search. On the left is taskbox called “refine research”, here you can refine by Subject area Document type Author Source titles Publication year Language Lets limit to last five years as we want current research  Click on Publication years  Click on more options/values  Check the boxes of 2006, 2007, 2008, 2009, 2010  Click on refine The number of results should decrease 5. SFX • Click on SFX to see if you can obtain full text. (If no full-text available, remember to check the library catalogue in case we have it in print and M25 Union list of serials to see if any neighbouring libraries have it) • If we have full-text click on Go and a new window/tab should open with the full-text of the article available to read. • Click back onto the Web of Science tab or window to see your results list again 9
  10. 10. 6. Search history • Click on Search History (at the top of the screen), here you can see the results you have created so far. • For the most recent set of results you can save search/create alert by clicking on the save search/ create alert button. • You will be prompted to name the search and you can also set up email alerts. Saved search means you can always access the search you did. By setting up email alerts, you will be notified when any new results for your search are added to the database. 7. Cited reference search This allows you to follow a strand of research through from one article to the next, by seeing who has cited a particular article that you know about.  Click the Cited Reference Search Here, I will look for all of Professor Ewing’s articles that have appeared in the Journal of Chemical Thermodynamics in 2002 (you need to enter the abbreviated title, using the abbreviations list). • Enter EWING M* into the author search box • Enter J CHEM THERMODYN into the cited reference box • Click on Search The next screen shows the articles that match your search query. You will see not just articles that have cited your article accurately, but also citations that the later articles have got wrong. No Link means that the citation might be wrong, look at the citation above and below to see whether the information is similar. It looks like 4 articles were published in 2002, however they have very similar details, so it is very likely to be the same article. • Tick all 4 boxes on the left • Click finish search. This will show us all the articles with both the correct and incorrect citations. That is the end of the demo, but don’t close the window we will use these results again later. Evaluation It is important not to accept information and ideas at face value but to take time to reflect, compare ideas, evaluate the work done and build your own reasoned arguments. Treat the information you find with caution. Remember to scrutinise and ask questions and don’t form conclusions until you see what others have written. 10
  11. 11. The ability to critically evaluate information is an essential skill for a researcher. Try using PROMPT, a structured approach to critical evaluation of information (Provenance, Objectivity, Method, Presentation, Timeliness) PROMPT checklist Item 1 Presentation (is the information clearly communicated?) Look at language, layout, structure, etc. Relevance (does the information match the needs of the searcher?) Look at the introduction or overview – what is it mainly about? Objectivity (Is the author´s position of interest made clear?) Look for an introduction or overview – do the writers state their position on the issue? Is the language emotive? Are there hidden, vested interests? Method (research reports only) (Is it clear how the data was collected?) Were the methods appropriate? Do you trust it? Provenance (Is it clear where the information has come from?) Can you identify the authors or organisations? How was it published? Websites- Look at the URL - personal page or site ? Domain name appropriate for the content ? Restricted: edu, gov, mil, a few country codes (ca) Unrestricted: com, org, net, most country codes (us, uk) Published by an entity that makes sense ? News from its source? E.g. www.nytimes.com Advice from valid agency? E.g www.nih.gov/ www.nimh.nih.gov/ Timeliness (Is it clear when the information was produced?) Does the date of the information meet your requirements? Is it obsolete? Thanks to the Open University Information Literacy toolkit for this section For web resources there are some key tools to help you check websites and evaluate them 11
  12. 12. Alexa - www.alexa.com • Click on “Site info for …” • Who links to the site? • Who owns the domain? Wayback machine - http://www.waybackmachine.org/ • What did the site look like in the past? Task 2: Try evaluating some sites Search a controversial topic in Google nuclear armageddon prions danger “stem cells” abortion Scan the first two pages of results Visit one or two of these sites Use PROMPT checklist to evaluate their quality and reliability Finding References in other Libraries http://www.ucl.ac.uk/Library/otherlib.shtml If you cannot get an article online you can try searching the UCL library catalogue (http://library.ucl.ac.uk) to see if there is a paper copy available. If there is not, why not try searching another Library? The Library web page (http://www.ucl.ac.uk/Library/otherlib.shtml) gives a thorough list of alternative libraries and websites where you can check for holdings of other libraries in and around London. Interlibrary loans If you cannot find a location for a book or journal that you require, it is possible to order an inter-library loan. This will cost £3. More information can be found on our website http://www.ucl.ac.uk/Library/ids.shtml. Citing sources It is important to include references in your work in order to indicate that you have used relevant information resources, to avoid plagiarism and to allow readers of your work to be able to find the information sources for themselves. You should remember to list all the details of the books/journals that you consult so that you can reference them correctly. Failure to cite your sources constitutes plagiarism and you may be penalised! Citing acknowledging within your piece of work the source from which you obtained information. Reference full details of the source from which you obtained your information. Bibliography a list of the references you have used, usually placed at the end of your text. For help with citing sources, 12
