UN Security Council documents have been issued since 1946 beginning with the document symbol element S/-
The basic format for the symbols of Security Council documents is:
All plenary documents of the Security Council, 1946-present, are available online.
See the information in the UN Documents Symbols & Series Symbols and the UN Security Council Documentation research guides for more information about particular types of documents and the documentation pattern overall.
From 1946-1964 Security Council resolutions were issued as S/-- documents.
In 1965, resolution numbers were assigned to all previously adopted resolutions, starting with S/RES/1 (1946) and finishing with S/RES/199 (1964). References to Security Council resolutions, 1946-1964, may cite the original document symbol or the S/RES/- symbol.
Revised annual compilations were issued for the years 1946-1964, in the S/INF/- series.
According to the Note at the front of the volumes of the revised annual compilations:
"The resolutions are numbered in the order of their adoption. The document symbol which appears in square brackets under the title of the resolution is the symbol that was used to identify the text before the adoption, in 1964, of the system of numbering used in the present volume, which has been applied retroactively to the resolutions adopted earlier by the Council."
The "Consolidated check list of resolutions of the Security Council, 1946-1964" (S/INF/19/Rev.1/Add.1) lists all retrospectively assigned resolution numbers and the original document symbol of the resolution.
Note: S/INF/4/Rev.1 and S/INF/5/Rev.1 are identical documents (except the symbol). ST/LIB/Ser.E/Cum.5, page 109, indicates that S/INF/4/Rev.1 is the correct symbol for the document originally issued as S/INF/5/Rev.1.

Annual compilations of Security Council resolutions, decisions, and presidential statements, cover the period from 1 August - 31 July, and form part of the Security Council Official Records (SCOR). They are organized by topic, not sequentially.
From 1994-2005, there were unofficial Press Release compilations which were issued much in advance of the official publication.
Presidential statements are first published as individual documents.
Before 1994, they were issued in the general Security Council series.
They are included in the annual compilations of Resolutions and Decisions.
Presidential statements are issued following consultations. There is no vote on a presidential statement.
Resolutions of the Security Council are first published as individual documents consecutively numbered since 1946.
All Security Council resolutions are included in the annual compilations of Resolutions and Decisions.
Adopted resolutions are usually voted on in open formal meetings of the Security Council. The vote is recorded in the meeting record.
An exception is the resolution recommending a candidate for Secretary-General to the General Assembly, which is adopted in a closed meeting with no recorded vote, in accordance with General Assembly resolution A/RES/11 (I) of 1946.
