Bibliographic Data Formats

This is a guide to bibliographic data formats that Zotero can work with. Most of these formats can be imported directly by Zotero, and some can be exported as well. Others are used only in conjunction with site translators and cannot be imported or exported directly.

For information on getting records into your library by using these import formats, you should probably consult the main documentation.

For troubleshooting import and export issues, you can consult the information below, but first try the relevant steps in the translator troubleshooting procedure and direct questions to the support forums.

The format descriptions here are very cursory– see the linked documentation and specifications for more details.

There is also a very outdated description of the mappings between Zotero fields and the fields in some of these formats.

RIS

Import and export

RIS is a simple plain-text reference format. It is nearly universally supported by reference management software and journal databases. The official specification was last updated in 2001, so reading the format is complicated by the frequent divergences from the specification. Zotero accounts for some of the more frequent non-standard uses in its import, but exports fairly strict RIS.

Translators that build off of RIS will frequently have to pre-process the RIS to account for non-standard use of tags.

Tools

  • Bibutils is a utility that can convert several of the formats above into and out of MODS XML, which serves as a very expressive intermediate format. This will often be more faithful than importing into Zotero and exporting in another format.
