Get a Scan is a free service for those currently affiliated with the university. Users may request scans of single book chapters and of articles --- these may be owned by the Libraries or not. There are limits: One chapter/article per request, and up to 3 chapters from a single book with individual requests. No scans of full books.
Ask for an item to be added to the library collection. "E" materials can usually be added quickly. Print takes longer. Also: We are glad to have suggestions for new subscriptions but can't start those right away.
If you aren't such which is the right match, please sure to ask for assistance.
