RIS (file format)
|Internet media type||
|Type of format||Bibliography|
RIS is a standardized tag format developed by Research Information Systems, Incorporated (the format name refers to the company) to enable citation programs to exchange data. It is supported by a number of reference managers. Many digital libraries, like IEEE Xplore, Scopus, the ACM Portal, Scopemed, ScienceDirect, and SpringerLink, can export citations in this format.
The RIS file format — two letters, two spaces and a dash — is a tagged format for expressing bibliographic citations. According to the specifications, the lines must end by the ASCII carriage return and line feed characters. Note that this is the convention on Microsoft Windows, while in other contemporary operating systems, particularly Unix, end of line is typically marked by line feed only.
This is an example of how the article "Claude E. Shannon. A mathematical theory of communication. Bell System Technical Journal, 27:379–423, July 1948" would be expressed in the RIS file format:
TY - JOUR AU - Shannon,Claude E. PY - 1948/07// TI - A Mathematical Theory of Communication JO - Bell System Technical Journal SP - 379 EP - 423 VL - 27 ER -

- The origin of the name RIS was obtained via email from Henry Johnson, a Customer Technical Representative at Scientific Thomson Reuters. Research Information Systems was owned by the Institute for Scientific Information (ISI). RIS, the creators of Reference Manager which had also previously bought ProCite from Personal Bibliographic Software Inc, merged with Niles software, the creators of EndNote. The result of the merger was the creation of ISI ResearchSoft, a subsidiary of Thomson Reuters, which produces Reference Manager, EndNote and ProCite. Email date 7/3/08.
