Green, Gold, Platinum, Nickel: On the Status of Open Access in Mathematics

[摘要] The various facets of Open Access (OA) have been a topicin the EMS Newsletter for many years, including articleson such diverse topics as a global description of the publishing ecosystem with its political ramifications [1] andthe concrete circumstances and policies leading to the flipof a single journal [2]. Recently, the announcement of theplan of cOAlition S [3] and the choice of Elsevier as a subcontractor to monitor the progress of OA by the EuropeanCommission triggered many reactions, including a statement by the EMS [4]. The aim of this note is to give a statusreport on the various OA facets in the mathematical corpus, which may also provide some quantitative information helpful to estimate the impact of envisioned changes.
