Request materials not owned by LVC via Tipasa, LVC's Interlibrary Loan system. Interlibrary Loan is a service that provides articles/materials you find from other libraries.
Almost every LVC Library database will provide a Looking for Full-Text? link on each result. If that fails to connect you to full-text, you'll be given an option to Request this Item through LVC Tipasa.
You can also request materials via Interlibrary Loan from the library's homepage.
With Interlibrary Loan, you'll either get a PDF of the journal or magazine article or a hard copy that will need to be returned.
Allow 2-3 days for an article; allow up to 2 weeks for books or media.
