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.[1] It is supported by a number of reference managers. Many digital libraries, like IEEE Xplore, Scopus, the ACM Portal, Scopemed, ScienceDirect, SpringerLink and Rayyan QCRI can export citations in this format. Major reference/citation manager applications, like Zotero, Mendeley, and EndNote can export and import citations in this format.

Format

The RIS file format — two letters, two spaces and a hyphen — is a tagged format for expressing bibliographic citations. According to the specifications,[2][3] the lines must end with 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.

Multiple citation records can be present in a single RIS file. A record ends with an "end record" tag (ER - ) with no additional blank lines between records.

Example record

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
T2  - Bell System Technical Journal
SP  - 379
EP  - 423
VL  - 27
ER  -

Example multi-record format

This is an example of how two citation records would be expressed in a single RIS file. Note the first record ends with "ER - " and the second record begins with "TY - JOUR":

TY  - JOUR
AU  - Shannon, Claude E.
PY  - 1948/07//
TI  - A Mathematical Theory of Communication
T2  - Bell System Technical Journal
SP  - 379
EP  - 423
VL  - 27
ER  - 
TY  - JOUR
T1  - On computable numbers, with an application to the Entscheidungsproblem
A1  - Turing, Alan Mathison
JO  - Proc. of London Mathematical Society
VL  - 47
IS  - 1
SP  - 230
EP  - 265
