Once you've found a book or article that's relevant to your topic, you can use it to find more that are about the same topic. Do not start by searching in subjects because these are "controlled vocabulary" meaning specific words are used for specific topics and these words are not always intuitive. For example, the subject term for the "Indianapolis 500" is "Indianapolis Speedway Race."
Researching forward, or reverse citation-searching or cited reference searching, is the complement to researching backward or citation mining. Take a book or article that is relevant to your topic and see what has cited it after publication. Note that it takes a long time to publish books (multiple years) and months if not years to publish peer-reviewed articles, so this technique doesn't typically work for very recent materials.
For the article referenced in citation mining, click "Cited by" on the results screen for Google Scholar:
The cited by link appears for both books and articles in Google scholar.
When an item has been cited many times, it may be useful to search within the citing items:
Once you've found an article or book that's relevant to your topic (or something your professor has recommended), you can use the bibliography or works cited to find more. This is called researching backward, or citation mining.
Read the bibliography.
Search for the title and author of the work cited. Google Scholar is great for finding articles. The library catalog is great for finding books.
For example, you might see this citation of an article written by Professor Ann Taylor and President Feller:
When you have the DOI of an article, use it in the DOI lookup tool:
You will be taken to a PDF version of the article, the article's page from the journal, or be able to place in interlibrary loan request, if Lilly Library does not have access to the article.
When you don't have a DOI, search the citation in Google Scholar (you can typically get good results with only the author(s) name(s) and the title of the article):
Get the result and click the Full Text @ Wabash link.

You might see this citation by a book written by Acting Dean of the College Todd McDorman
You can search the library catalog for the book. You will generally get good results with the author(s) name(s) and the title:
And here is the book and its availability from the library:
