Discovering More Sources by Following the Citation Trails
Need to find more information on your topic?
You (or someone you know) have probably used a Wikipedia article to find sources. Find an entry on your topic, check the references - and you've got some sources to start exploring your topic!
You can do the same thing with journal articles and books. When you find a source that is particularly relevant or useful for your topic, you can look for books or articles your source has referenced. Finding one good source will help you find others!
For example: The Wikipedia entry on Macbeth contains this footnote:
Clicking the hyperlinked footnote number brings us to the footnote:
Looking through the references using the author's last name comes up with this reference:
A search in the Library General Search comes up with the book chapter, which can be read online. A Wikipedia article has helped find a scholarly source!
Some Library databases have tools that will help you track citations. Check an item record to see if there is a link or a list for the item's references, or a link or a list for publications citing the item.
If you notice an item with a very high "cited by" count, many other authors have found it valuable, and it might be worth investigating. The Scopus Database is a very good resource for this purpose. It is designed to display an item's references, as well as publications citing it.
When you're reading and find a reference that looks useful or interesting, you can look at the works cited (usually found at the end of an article, chapter, or book).
You can use the Library General Search, Google Scholar, or WorldCat to check if the Library has access to the item you've found. If the Library doesn't, don't panic! You can still make a request using interlibrary loan. One good source will help you find others.
Reference books (encyclopedias, handbooks, guides, companions) are great places to find entries with bibliographies or references to related articles or books on your topic.
The Encyclopedia of Food and Culture (2003) includes an entry on "Snacks" with a brief bibliography of related book titles.
Search in Library General Search, Worldcat, or Google Scholar for items listed in the references.
Wikipedia is one place to find background information. In addition to Wikipedia, the library subscribes to multiple online reference resources that are as simple to search as Wikipedia, but return results written by experts in the field with more comprehensive bibliographies containing a higher number of scholarly sources.
