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 Under the Get Help & Support pull down at the top of the page.
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.
Dissertations and theses may be found in several sources.
Find dissertations and theses in WorldCat Dissertations, a resource that points to citations/abstracts of dissertations and theses published in the US, Britain, Canada, and other European countries.
Try also Dissertations and Theses A&I.
Both WorldCat Dissertations and Dissertations A&I will require the use of Tipasa, or interlibrary loan to obtain a copy of the dissertation/thesis.
