Hat tip to Chuck Jones at AWOL, the Databases About Aegean Subjects Project contains scholarly bibliographies and bibliographic databases. The following has been added to the Bibliographies Page at this site and to the Zotero Group for Ancient World Open Bibliographies.
Cretan Heiroglyphic Gyptic (bibliographic database)
Mycenological Publications of Scholars of the Former Soviet Union (list of items, almost all in Russian)
Three other bibliographies are listed on this page but appear to not yet be active.
University of Florence.
Appears to be currently updated.
There is also a bibliographic database of Minoan and Mycenaean Bibliography Since 2006.
