Established 1996 — the Electronic Library of Mathematics (eLibM) is the longest-running and largest open access repository in mathematics.
The Electronic Library of Mathematics contains online journals and proceedings in the field of mathematics. All material is in electronic form and access is generally free, except for some periodicals with a "moving wall", i.e., a certain delay period after which resources become freely available.
Some requirements have to be fullfilled for a journal or proceedings volume to be included in the Electronic Library. For these please refer to the eLibM guidelines.
There is also the possibility for publishers to organize the publishing workflow with eLibM.
