2003 and in-session documents:
Explanation of document symbols:

Official documents are issued under a masthead bearing the UN and UNFCCC logos and with a UNFCCC document symbol. Official pre-session documents are available before the meeting, usually in all six official UN languages (Arabic, Chinese, English, French, Russian, Spanish). Post-session documents, normally the reports of a session, are also available in all six official UN languages. In-session documents are available only during meetings ( CRPs, Ls, MISCs). L documents are normally translated. CRPs and MISCs are available only in the original language of issue.

UNFCCC documents document symbols include designators for the relevant Convention Body ("CP" for the COP, "SBI" or "SBSTA" for one of the subsidiary bodies, or "SB" for documents prepared for both subsidiary bodies), and the year in which the document was prepared. In addition, the following designators are used:

/INF.- This suffix denotes the Information series. These documents are not translated and are available in the original language of issue for general distribution.

/MISC. - This suffix denotes Miscellaneous documents. These documents are not translated and are issued on plain paper with no UN masthead and are available for general distribution. In the UNFCCC process, submissions by Parties are normally issued as miscellaneous documents.

/Add. - This suffix indicates an addition of text to the main document. The distribution category depends on the parent document.

/Rev. - This indicates a new text (Revision) superseding and replacing that of a previously issued document.

/Corr.- This suffix denotes corrigendum documents. It indicates modification of any specific part of an existing document to correct errors, revise wording or reorganise text, whether for substantive or technical reasons. The language of availability and scope of circulation depends on the parent document.
