The Palazzo Falson Library Catalogue operates via a set of active string filters. You can use one field or multiple fields to enter search data. Simply add the desired search information into the desired field(s). The search will automatically update the number of records based on the search criteria. One can narrow the search by selecting multiple fields at a time (e.g., "Brown" as author, and "London" as place of publication) or by selecting a medium type (or types). To search for items digitized by HMML, simply enter "PFL" in the HMML field to get the complete list, or simply enter the exact HMML Project Number (e.g., PFL 00001).
