Comparison of reference management software
The following tables compare notable reference management software. The comparison includes older applications that may no longer be supported, as well as actively-maintained software. General. In the "notes" section, there is a difference between: Operating system support. In the case of web applications, this describes the server OS. For centrally hosted websites that are proprietary, this is not applicable. Any client OS can connect to a web service unless stated otherwise in a footnote. Export file formats. This table lists the machine-readable file formats that can be exported from reference managers. These are  typically used to share data with other reference managers or with other people who use a reference manager. To exchange data from one program to another, the first program must be able to export to a format that the second program may import. Import file formats are in a table below this one. Import file formats. This table lists the file formats which may be manually imported into the reference managers without needing to connect to one particular database. Many of these database companies use the same name for their file format as they do for their database (including Copac , CSA, ISI, Medline, Ovid, PubMed, and SciFinder). For the ability to retrieve citations from the particular databases (rather than the file format), please refer to the database connectivity table that is below this table. , CSL YAML is not supported by any reference management system. Reference list file formats. Endnote is incompatible with LaTeX. Among other things, it does not provide for robust citation keys. Word processor integration. Some reference management software include support for automatic embedding and (re)formatting of references in word processing programs. This table lists this type of support for Microsoft Word, Pages, Apache OpenOffice / LibreOffice Writer, the  LaTeX editors Kile and LyX, and Google Docs. Other programs are able to scan RTF or other textual formats for inserted placeholders which are subsequently formatted. Most reference management programs support copy/paste or drag-and-drop of references into any editor, but this is not meant here. Database connectivity. This table lists the academic databases and search engines which reference managers can import from. In some cases, a search and retrieval can be conducted directly in the reference manager. In others, a bookmarklet or Firefox extension will allow a site to be scraped. Password "protection" and network versions. Some  reference managers provide network functionality. (N/A means the product has no networking, while "no" indicates it does (but lacks an implemented feature).)
