Bookends is a full-featured bibliography, reference, and information management system for students and professionals. Bookends requires macOS 10.13 or later.
A highly configurable, interactive, and editable interface lets you work with reference information the way you want. View Groups or Term Lists (Authors, Keywords, etc.) on the left. In the concise reference view on the right, arrange fields in any order, show just the ones that you find useful, and label them as you like. Editing or entering information is a single click away. Show attachments (pdfs, text files, images, etc.), or use the reference’s URL to show live web pages of its contents. Notecards let you enter, edit, and rearrange your thoughts, and make citing pages in footnotes a snap. Tag clouds let you visualize your terms and word use, and quickly tunnel down to the references you want.
