Hello,
Jose Chess Database version 1.4.1 is available for download from:
http://jose-chess.sourceforge.net/index_download.html
Jose features now a UI opening book.
It can read book files in the Polyglot and Crafty formats
(and, of course, engines can have their own book files).
As usual, downloads are available for Windows, Linux and Mac OS X.
Have fun,
Peter
