Books are usually loaned, while photocopies of journal articles are usually sent for you to keep instead of loaning the whole issue. Technical literature in fisheries and wildlife can be especially problemmatic because many sources are unpublished state agency reports. Ask a librarian for help if you are not sure about the type of material you are requesting. It usually takes 2 - 3 weeks to obtain a book loan or photocopy. Ask at the information desk for help with interlibrary loan requests.
Many indexes abbreviate the titles of journals.
If you don't know the full title, attach a copy of the index printout or ask at the Reference Desk. If you have a number of requests on computer printouts, you can submit those rather than copying the information on to request forms. Ask at the Reference Desk about this shortcut. Some fish and wildlife agencies are starting to put their reports on the web. If you find these they may be very useful.
