I've updated my overview chart for reference managers. Added Citavi (popular in Germany) and a few categories. PDF can be found here: http://www.slideshare.net/mfenner... - Martin Fenner

Nice work. Another useful category would be import/export formats supported, e.g. BibTeX is important for me, but there are also other standard formats. - Matt Leifer

Matt, I did not include import/export, because all of them support RIS, and almost all of them Endnote and BibTex. Moving your references to a different reference manager is not really an issue (moving the fulltext files is more difficult). - Martin Fenner

Fair enough. I think the *quality* of the import/export varies significantly though. An important question is whether you get essentially the same file back when you import and then export to the same format. Papers is terrible at this because it converts everything to a "paper" so you lose all of the information about the category of the object you are citing. This makes it awful for managing bibliographies for LaTeX/BibTeX and you are better off going with something that is BibTeX native, e.g. Jabref or bibdesk, to avoid information loss. Actually, I think I've just ranted myself into coming up with a good new category for the overview -- what is the native format that reference data is stored in and is it an open format or proprietary? - Matt Leifer

Zotero supports saving items from Scopus, and offers metadata retrieval for PDFs (http://www.zotero.org/support...). - Rintze Zelle

Matt, I give all papers relevant to a manuscript or proposal that I am writing a specific tag via the "Notes" field, and when you search in Papers for that tag in that field, you get a list of all the relevant articles, which you can then export as a .bib file. Some cleanup required (replacing "notes =" with "notes1 =", so as to avoid the tags appearing in the bibliography, similar for the global and local url fields), and all is fine, though it would be nice to be able to configure the export such that notes and urls are excluded by default. Anyone from mekentosj around? - Daniel Mietchen
