Over 30 years ago a renowned Hamlet scholar expressed his astonishment that some 400 works a year dealing with the play were being received at The Shakespeare Quarterly. The rate of Hamlet studies has increased quite considerably since then. To make any headway in the study of any aspect of Hamlet, the use of bibliographies—annotated, if at all possible—is often necessary.The most up-to-date resource is the Folger Shakespeare Library in Washington, D.C.; their publication, The Shakespeare Quarterly, has one issue per year devoted entirely to bibliography. As to their on-line searching, a search of the keyword "Hamlet" in Folger's web-based catalog, Hamnet (accessed 1/25/2008) returned 2245 entries; the result does not include the number of entries in the library's card-catalog.
