Many digital libraries, like Web of Science, IEEE Xplore, Scopus, the ACM Portal, Scopemed, ScienceDirect, SpringerLink, Rayyan, The Lens, Accordance Bible Software,[2] and online library catalogs can export citations in this format.
The RIS file format—two letters, two spaces and a hyphen—is a tagged format for expressing bibliographic citations.
[6][9][10][8] Unless otherwise specified, each date must be formatted as a slash-separated list of 4-digit year, 2-digit month, 2-digit day, and other info (e.g. season); unused fields may be omitted if they are at the end.
These are only sometimes noted in the table below; see the linked sources to double-check, particularly [9] and the pages in RIS Format Specifications.
There are two major versions of the RIS specification, one from 2001, and one from the end of 2011 with different lists of tags for each type of record, sometimes with different meanings.
