  Export file formats
  This table lists the machine-readable file formats that can be exported from reference managers.

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.

  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.
