iPapers 2.2 (Toshihiro Aoyama)

From the site: "iPapers is an application that manages many PDF files of articles, whose information can be obtained by PubMed. If you have articles as PDF files whose filenames are PMID.pdf (e.g. 10867176.pdf), you can import the articles into iPapers by drag and drop operation. PMID is the unique ID provided by PubMed. iPapers automatically searches and imports the information of the imported articles from PubMed DB, e.g. name of authors, title, journal name, volume, number, pages and abstract. iPapers not only manage the articles with PDF named PMID, but also manage a PDF file which is not listed in PubMed and a reference information without PDF."

Papers 1.7 (mekentosj.com)

From the site: "Do you have dozens of PDF files from your favorite scientific articles scattered on your harddrive? Do you also try to desperately organize them by renaming and archiving them in folders? But like the piles of printed articles on your desk, you can't keep up with all the new papers you download, and despite all your efforts it has become impossible to find that one article. Finally that all belongs to the past. We've been there, trust us, we know. That's why we wrote Papers, our latest application exclusively for the Mac. Papers will revolutionize the way you deal with scientific papers. Search for papers using PubMed, directly retrieve and archive PDFs, and read and study them all from within Papers, your personal library of Science".

From the site: "Reference Miner searches the Internet to find and display reference information from PubMed, Amazon (US, UK, Germany, and Japan), and the Library of Congress.

Synapsen 3.0 (Dr. Markus Krajewski)

From the site: "synapsen is a hypertextual card catalog, which is to say a storage system on the basis of an electronic literature databse that enables the management of bibliographies. However, in contrast to normal literature management software, synapsen offers a very distinct advantage: with catchwords entered by the user, the program connects individual cards automatically and creates not only a network of cards whose relation to each other might have been forgotten, but also creates completely unexpected connections and relations between individual entries. synapsen is therefore not only for electronic literature management, but also a helping hand when writing scientific texts, which participates in communication with the author in order to augment lines of argumentation and the generation of ideas."
