The Swiss Mathematical Society donates their records and documents to the Archives and Private Collections of the Library of ETH Zürich on a regular basis. An agreement between the SMS and the Library determines the terms of transfer, safekeeping, access and authorizations. Please see also the user rules and regulations.
Modus operandi: Records of the committee are sent to the archive in every year x = 0 mod 5. The same rhythm applies to records of the accounting, but only for relevant documents that are older than 10 years. The SMS office keeps all accounting files for 10 years.
