Pre-Classical Greece
Studies in Mycenaean Inscriptions and Dialect (SMID)
http://smid.class.utexas.edu
Program in Aegean Scripts and Prehistory, Department of Classics, University of Texas, Austin.
Currently being developed; as of July 2011 the database contains works published between 1979 and 1999, with progress underway on further updates.
SMID is an analytical bibliography of Mycenaean text studies, now available as a searchable database containing approximately 2000 works (articles and monographs in multiple languages). Searches can be conducted by (Linear A or B) words or parts of words, or by author, title, or source. Short summary abstracts are provided for works included.
(Updated to add new & improved link, though the old one still works.)

Thanks for posting this! We’re still in Beta but everything on the website is functional. We also updated our URL to http://smid.class.utexas.edu, but the old one works as well (the paspserver one). It’ll be great if you can update your links to the new one!
I will update the links! Thanks for the note.
