This page is aimed at students looking to go beyond recommendations and start a literature search. You can try this in iDiscover, but you should also make use of the extensive online databases at your disposal. There is an A-Z database LibGuide to help you choose those most relevant to your subject area. Most of the ebooks and journal articles indexed in these databases cost money to view. The university pays for access to a significant portion of this research. If you are off campus, you need to make sure you are logged in via Raven to get access to everything to entitled to. Always link via the library webpages rather than just Googling the name of the database.
However, you will find material that we haven't paid for and so you cannot access. The Wolfson College Library can buy books that we don't have, just fill in the Suggest a Book form, or you can get a copy of an article through the Inter library Loan scheme.
You can also use free databases such as Google Scholar. This indexes the widest range of material but doesn't give you access unless Cambridge subscribes to it. To find out whether you have access to online resources in Google Scholar, you need to set up Library Links. Watch the video below to find out how.
When you don’t have a specific reference to help you find a relevant book or journal article you’ll need to conduct a literature search.
Define your information need: do you want to one relevant result or everything ever published in a field? The answer to this question will shape where you look for resources and the type of search you conduct.
Articulate your search terms: Think about:
Please note that the symbols you need to use vary between different databases. The University of South Australia has produced a useful document showing some of the variants.
Select your tools: are you after a book by a renowned author held in Wolfson library, a freely available government publication, an e-journal article you can view on your laptop in your room, or a thesis to find out the latest research? You’ll need different search tools for each. See the A-Z list of databases.
Evaluate your results: How many did you get? Do you need to broaden your search? Be more specific by adding additional search terms (use AND) or expand your search by giving alternatives (use OR). Limit them by country of origin, date or funder. Again, different databases will give you varying degrees of granularity.
Here's how a strategy could look. The research question is defined at the top and the grid breaks it down.
Entered into a database or search engine it would look like this:
nuclear AND (soci* OR commun*) AND (impact OR outcome* OR effect*) AND (power OR energy) AND NOT (weapon OR bomb OR proliferation)
Plan your own search strategy using this grid
No search is perfect and it is likely that you'll end up with too many or too few results. If you have found a really useful book or article there are several ways of using that item to find related books and journal articles. Here we introduce Browsing and Citation Searching.
When you find something that is relevant it makes sense to use it as a springboard and connect you to other related material. There are a number of ways to do this for books on iDiscover:
Browse the shelves: Books are arranged by classmark. The classmark is a number that links similar material together. You’ll find it on the spine of the book and the numbers on the end of the bookcases tell you which classmarks are on those shelves.
Use author search for related material: It is probable that an author has published more than one book on a topic. Scroll down to foot of the iDiscover record and look at the information under 'Details' (see image below). Click on the author to find other works by the same person. If you start from the Advanced Search on iDiscover, you might want to add a keyword or date range to exclude authors with the same name.
Use subject headings in iDiscover: this is just like browsing the shelves. Each book is assigned subject headings (see below). Click on these to find books on the same topic.
This is a great way to find related material. You can either find out who else has cited the work you are interested in or follow up the resources that are cited in the bibliography.
Databases such as Web of Science can give you a greater variety of citation options. This screen shot shows that you can follow up 86 articles that have cited this article (AND are indexed in Web of Science), 53 references in the bibliography, and find related records. These are articles that share at least one or more references with the original. Some of these results will be in your original search, but many won’t because they don’t share your search terms (keyword or title, depending on what you searched for originally).
Google Scholar is well known for linking to the most citations because it indexes so many books and articles. You can see that for the same article as above, it finds 386 resources that cite it.
