Seek and ye shall find
Import references and PDFs (access privileges may be required) from PubMed, PubMed Central, Google Scholar, JSTOR, Google Books, Web of Science, arXiv, the Library of Congress, and hundreds of institutions around the world.
Play nice with others
Integrate your work with other applications: import references from EndNote, Papers, Sente, Zotero, and Mendeley; insert into or embed in Bookends live links for applications such as Tinderbox, DEVONthink, and Scrivener; enjoy integration with Microsoft Word, Mellel, and Nisus Writer Pro. And like all good macOS-native apps, Bookends is AppleScript-able.
Bookends is reason enough to switch to a Mac.
Everything in its place
Unlimited multi-level hierarchical folders and groups (static and smart) bring your reference data soup into coherence. Identify and reuse recurring data from self-updating Term Lists.
Attach PDFs, images, Word documents, or anything you want. Let Bookends rename and organize your attachments in a central location. Search your library for references and the contents of their attached PDFs simultaneously to find just the articles you want.
The full-featured PDF reader lets you add markup and annotations, which automatically integrate with the interactive note stream. Share annotations with other PDF readers and Bookends for iOS (of course). Create deep PDF links for instant access to your annotations and thoughts while in other applications. Bookends can even extract attached PDF annotations with full details and links from one or all references in one go. And a tabbed PDF display lets you switch between references and their PDFs with a click.
No book is an island
Like people, references may be related. Create links between items such a book and its chapters, an article and the works it cites, or any other relationship you can dream up. See all relatives at a glance, move between them with a click, and even combine portions from each in a single bibliographic citation.
Have Bookends create hypertext links to references, groups, folders, and PDF content. Connect references to apps in the outside world, and vice versa. Take logical jumps from one reference to another, and back again. Follow the interconnecting breadcrumbs, one click at a time.
Every cloud has a silver lining
Tag clouds are visual depictions of the terms in your references, and each tag's frequency is indicated by size and color. They're not just pretty, they let you quickly winnow the references to just the ones you want.
Think locally, act globally
Curate your library using a plethora of global operations. Find/replace, consolidate related names and terms, move fields, change case, standardize names, and more allow you to instantly update one or all of your references and PDFs with a click.
Bookends uses iCloud to effortlessly keep your references and groups in sync across all of your devices, so you don't need to schlep your databases from one computer to another. Share libraries with colleagues using Bookends, so everyone in your group is up-to-date. And with our companion app, Bookends for iOS, you'll always have current information with you, wherever you are.
Float (and cite) like a butterfly
Double-tap the Control key while in any word processor to bring up Floating Citations. Searching, citing, viewing PDFs, and more are at your fingertips, all the time.
Do it with style
Publishers impose strict rules on how citations and bibliographies appear. Bookends provides an intuitive format editor with which you can use or modify the hundreds we already ship, or create your own.
Get it in writing
Scan word processor manuscripts to create publication-ready documents complete with in-text citations, footnotes, and bibliographies. Scan directly from within Microsoft Word, Mellel, and Nisus Writer Pro, or scan Apple Pages, LibreOffice, and RTF files from within Bookends. In just a few moments you're ready to submit and publish.
Definitely worth it if you are looking for an easy and effective way to reference and cite your work.”
