AMS Open Access Journals
AMS Open Access provides unrestricted electronic access to AMS peerreviewed scholarly research. AMS research journals fall under two models of open access, green and gold:
AMS Green Open Access Journals
With green open access, the author may post a prepublication version of a journal article on their personal web page, on their institution’s noncommercial repository, and on arXiv.org. The author may post the final peerreviewed manuscript including revisions that take into account comments and suggestions of referees. In this model, there are no processing fees and the article is included in a subscription journal. All AMS subscription research journals are green open access journals.
AMS Gold Open Access Journals
With gold open access, the AMS makes the final published version of an article freely available electronically immediately upon publication. The AMS offers four gold open access journals: Proceedings of the American Mathematical Society, Series B, Transactions of the American Mathematical Society, Series B, Conformal Geometry and Dynamics, and Representation Theory.
There are two types of payment structures for AMS gold open access journals:
Gold Open Access with No Article Processing Charge (APC)
Two AMS journals do not require payment of an Article Processing Charge for publication: Conformal Geometry and Dynamics, and Representation Theory. In this model, articles appear online and are free immediately upon publication.
Gold Open Access with Article Processing Charge (APC)
Two AMS journals do require payment of an Article Processing Charge: Proceedings of the American Mathematical Society, Series B, and Transactions of the American Mathematical Society, Series B. In this model, it is generally assumed that an Article Processing Charge (APC) will be paid by a funding agency or by the author’s institution. APCs are not expected to be paid by the author personally. Resources for finding Open Access funding can be found here.
Proceedings of the American Mathematical Society, Series B, and Transactions of the American Mathematical Society, Series B will serve as separate and distinct companions to the subscription journals Proceedings of the AMS and Transactions of the AMS. Each of the new journals is electroniconly and freely available online, supported by Article Processing Charges designed to cover the Society’s publication costs. In order to ensure the high editorial standard of each new journal, Proceedings of the AMS, Series B, and Transactions of the AMS, Series B, share common editorial boards, and thus submission procedures, with their companion journals. In addition, editorial decisions are completely independent of whether a paper is intended for the open access journal or its subscription counterpart.
The gold open access option is available for all articles accepted by the Proceedings of the AMS and Transactions of the AMS editorial boards. New articles should be submitted via www.ams.org/procsubmit or www.ams.org/transubmit. Upon acceptance of an article, the author(s) may choose open access publication. Publication in one of these gold open access journals is dependent upon payment of the APC by a research sponsor or the author’s home institution.
Article Processing Charges (APCs)
In the gold open access model, it is generally assumed that an APC will be paid by a funding agency or by the author’s institution. APCs are not expected to be paid by the author personally. If an author chooses the gold open access model, payment of the APC is required before the article will move into production; only those papers with paid APC will enter the open access journal queue.
The Article Processing Charges are:

Proceedings of the AMS, Series B: List Price US$1,500
(Discounted price through end of 2016: US$750)

Transactions of the AMS, Series B: List Price US$2,750
(Discounted price through end of 2016: US$1,400)
Special offer for the first five papers published in Transactions of the AMS, Series B, in 2016! Pay only US$750!

Creative Commons Licenses
Articles published in an AMS gold open access journal will be distributed under the terms of one of the following licenses:

The Creative Commons AttributionNoncommercial License (CCBYNC), which excludes commercial use. This license lets others remix, tweak, and build upon the article noncommercially; the new work must credit the original article and be noncommercial.

The Creative Commons Attribution License (CCBY) [NOTE: This license is mandatory for compliance with the RCUK policy (United Kingdom) and therefore required for any EPSRCfunded paper published under open access.] This license lets others distribute, remix, tweak, and build upon the article, even commercially, as long as credit for the original article is given.
Authors will retain copyright to their articles under both CCBYNC and CCBY.
Publication Backlog
Backlog information for the green open access subscription publications is available here:
Articles in these journals are published in order of the last revision date as submitted to the editors via EditFlow.
The gold open access APCsupported publications, Proceedings of the AMS, Series B, and Transactions of the AMS, Series B, do not currently have a backlog. Articles in these journals are published in order of the date the gold open access publication decision was communicated to the AMS.
Open Access Policies
The AMS is currently fully compliant with existing open access policies from international research institutions, research funders, and governments including:
The AMS is looking at how best to work with federal funding agencies to help implement policies that will offer the mathematical community a rich range of publishing resources, digital innovation, and distribution and archiving models that will contribute to reduced government costs and improved efficiencies. The AMS will continue to support enhancing public access to content, while supporting the ability of the AMS to serve its membership.
