Interlibrary Loan (If you cannot find a research paper or a book chapter online or at the University Library, you can request it through Interlibrary Loan. Log in to this page with your IU username and password, and hit the "New Request" button on the menu bar.

zbMATH Open (to find a published paper)
Overleaf (If you have a Purdue email address, you can use the premium version for free, although the standard version has no problem.)
Department of Mathematical Sciences Thesis repository (Reading someone's Introduction is probably the best way to learn the basics of the area of mathematics that the author is interested in.)
Travel Award by the School of Science Graduate Student Council (Fill in the application form on the SOSGSC website, then send it to Mr. Joseph Thompson (jlthomp@iu.edu). Since the SOSGSC website is obsolete, there could be an update on the webpage soon; if anything is unclear to you, please write an email to Mr. Thompson for further questions.)
