Library catalogs are good places to begin looking for books & e-books by keyword, author, title, or subject. These database do NOT search the content/text of books however.
Looking for a journal? Search by the title of the journal (not the title of the article).
The books in Geisel Library are arranged by a system called Library of Congress Classification. The letters and numbers ("CALL NUMBERS") on the label applied to the spine of each book represent this classficiation. The call numbers are used to keep the books in order, arranged by subject and subarranged by author. Books on the archaeology of a particular region or culture will be with books on the broader topic. For example, books on archaeological topics pertaining to Turkey will be shelved with other books on Turkey in the range of call numbers beginning with DS 156.
General books on archaeology are on the fifth floor, in the area with call numbers beginning with the letters CC. For more information about how archaeology books are arranged within the CC classification, go to the offical Library of Congress page.
