Sonny Software has issued Bookends 13.0.2 with automated repair of damaged indexes (resulting in fewer suggestions to rebuild) and improved cloud sync to minimize requests for authentication from Apple. The reference management tool also updates Copy Citation and scanning to work with Microsoft Word 16.x, updates import from Google Scholar to deal with changes made by Google, improves detection of a linked word processor, fixes a bug that prevented PDF page numbers from being updated in the reference edit pane/window, and improves metatag searches (so tha they work when tags contain spaces).
A free trial that’s fully functional for up to 50 references is available. If you purchased a Bookends license more than 2 years ago (Bookends licenses provide 2 years of free updates), you can upgrade to version 13 for $39.99. ($59.99 new with a 25 percent discount for TidBITS members, $39.99 upgrade, 45.1 MB, release notes, 10.9+)
