From the project website (accessed 2016-01-08):
The database Glossarium Græco-Arabicum makes available the files of a lexical project, intended to open up the lexicon of the mediæval Arabic translations from the Greek. It contains images of the filecards (ca. 80,000) which have not yet been published in the analytical reference dictionary A Greek and Arabic Lexicon (Leiden: Brill, 1992ff.), and comprises Arabic roots from the letter jîm to the end of the Arabic alphabet.
