Reference management entails the collection, annotation, curation, and citation of published information. Bookends simplifies these tasks. 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, and virtual), term lists (keywords, authors, etc.), reference cross-linking (links), multiple notecards per reference, PDF annotation, tag clouds, 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 On Tap 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, Mellel (including Live Bibliography, updating of citations and bibliographies as you type), Apple Pages '08, ’09, and (provisionally) Pages 5, Nisus Writer Pro, and OpenOffice 3.
