RAMBI is an excellent multi-langugage bibliography of articles in Jewish studies and the study of Israel. The records are citations (not abstracts or the full-text) of journal articles, and some books, that have been cataloged by Hebrew University. You will need to go back to the WU Catalog to see if we have access to or own materials you find in RAMBI.
