To find books and government documents in USA Libraries' collections, use SOUTHcat: USA Libraries' Catalog.
Catalog tips and tricks:
Keyword searches – use quotation marks to hold phrases together ("missing in action")
Truncation – use ? after the root of a word to find all its variants (e.g. “Vietnam?” can be used for either Vietnam or Vietnamese)
Browse the Subject(s) field in records to find the right words for searches. (Example: Try doing a keyword search for "POW",and "Vietnam" then look at the subject(s) field in several records. You’ll see that the subject term is "Prisoners of war--Vietnam." Click the subject heading to find more records with this subject.)
Revise and refine your searches.
Watch for repeating call numbers and browse stacks in that area.
