Most library databases are provided through common services such as ProQuest and EBSCO. These services will allow you to create an account (that works across all the individual databases the Libraries subscribes to from each platform, i.e. EBSCO for Criminal Justice Abstracts and Academic Search Complete, ProQuest for Sociological Abstracts and Worldwide Political Science Abstracts). Once you create an account, you can usually do things like save and annotate records for later review, get emails with links to new articles that meet a search criteria, etc. This is a good way to keep track of articles that you think you may want to use in a paper.
The Libraries' Search It catalog also has a My Favorites list that (once you are logged in) will let you pin books and article records, add a brief note, and more. Note: You don't actually have to be logged in, but if you are not, your pinned Favorites will disappear at the end of your Search It session.
At WSU, a colleague teaches EndNote classes (see the box below this one) and I (Lorena) teach Zotero classes. I believe that Zotero is an excellent tool for online and in-person students - in addition to storing your articles, citations, and notes on your desktop/laptop, you can also choose to store all your references and notes online (along with PDFs and other files as well), so you have access to them anywhere with an Internet connection (and it it works nicely with tablets). If you would like to learn more about Zotero, check out the links below. If you would like to schedule an online class/webcast/consultation, contact me directly.
