From their facebook page-
A new search tool which facilitates the exploration of the Taylor-Schechter Cairo Genizah Collection is now available.
The keyword metadata provides a new way of searching and browsing the Collection both across broad subject areas and around distinctive items of vocabulary or key concepts. Furthermore, the interface is able to suggest similar items that might be of interest to the user, based on the similarity of the accrued data.
You can find the search slider here:http://cudl.lib.cam.ac.uk/collections/genizah by scrolling to the bottom of the page. A login is required (various login options are given).
