Reference management entails the collection, annotation, curation, and citation of published information. Bookends greatly 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, 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.
