The best way to save an article is (still) to download the PDF if that option is provided. However, you can also look for the "envelope" icon to e-mail yourself the article link--though remember you'll still need to log into the portal to access it from your home computer. If you use a single database enough, you can also create your own account within the database (though you'll lose access to this material after you graduate).
We have several different ways to get help if you get stuck.
Past Senior Projects
Senior projects through 2009 are kept on pre-digital "microfiche" slips and can be accessed by stopping by the Research Help Desk in the back of the library's 2nd floor. You can search for them using OneSearch from the library's homepage: https://lib.calpoly.edu
