Bookends  version 12.8.4
The reference manager you’ve been looking for

Now with 100% more cloud sync! In addition to all the great features that make Bookends invaluable in your academic life, you can now seamlessly synchronize your reference libraries and attachments between all your Macs as well as Bookends for iOS on your iPad or iPhone (cloud sync requires macOS 10.10 or later). Cloud sync is fast, secure, and transparent. Even if you have only one Mac and no iOS devices, using cloud sync gives you a secure backup of your reference library. Here is a list of what’s new in this version of Bookends.

Download and use the introductory version of Bookends for free. It will not timeout and is fully functional except for a 50 reference per library limit. If you need more than that, you can purchase Bookends and the registration code you receive will allow an unlimited number of references per library.

Moving from another reference manager (EndNote, Sente, Papers, Zotero, Mendeley)? You can easily transfer their references and PDFs to Bookends.

Collect, find, organize, annotate, and publish with Bookends

Reference management entails the collection, annotation, curation, and citation of published information. This is exactly what Bookends does. Bookends can perform Internet searches to retrieve references and associated pdfs or web pages, or immediately find and import references for which you already have the pdf. Versatile groups (static, smart, hierarchical, and virtual), Term Lists (keywords, authors, etc.), reference cross-linking (links), multiple notecards per reference, searchable PDF tags, PDF annotation, on-the-fly creation of tag clouds of reference information that can be organized into hierarchical metatags, and instantaneous live searches help organize and find information in your personal collection. Highly configurable displays let you view the reference information and attachments the way you want. Scan your word processor manuscripts to create publication-ready documents complete with bibliographies and footnotes. Sync references and pdfs in your library with your iPhone, iPod Touch, or iPad (requires separate purchase of Bookends for iOS from the iTunes App Store). Create and edit PDF annotations and highlighted text, which instantly appear as Bookends notecards. And much more. Compatible with
Microsoft Word 2011 and 2016, Mellel (including Live Bibliography, updating of citations and bibliographies as you type), Apple Pages '08, ’09, and Pages 5, Nisus Writer Pro, Manuscripts, and LibreOffice/OpenOffice 4.

Bookends is a CNET Editor’s Pick and a MacUpdate featured app, with 4-5 star user reviews.
