The free introductory version of Bookends will never timeout and is fully functional except for a 50 reference limit per library. To run it you will need a Macintosh running Mac OS X 10.6 (Snow Leopard) or later. To activate the feature that allows you to enter unlimited references, please fill out the secure order form or contact Sonny Software to buy Bookends and receive your registration code.
Note: Bookends 12.x is a paid upgrade for owners of Bookends 11 and earlier and requires a new serial number. It is free for anyone who bought or upgraded to Bookends 11 on or after January 1, 2013. The upgrade price for a single license is $29 for those who bought Bookends before January 1, 2013—see our order page for details and prices for upgrading group licenses.
