AMS Open Access provides unrestricted electronic access to AMS peer-reviewed scholarly research. AMS research journals fall under two models of open access, green and gold:

**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 AMS considers any version of the paper up to the final peer-reviewed manuscript including revisions that take into account comments and suggestions of referees to be a prepublication version. 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. Green open access journal articles are free to the public five years after publication.

**With gold open access,** the AMS makes the final published version of an article freely available electronically immediately upon publication. The AMS offers two gold open access journals: *Proceedings of the American Mathematical Society, Series B*, and *Transactions of the American Mathematical Society, Series B**. *Each of these journals requires payment of an **Article Processing Charge (APC).** In this model, it is generally assumed that an Article Processing Charge 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 electronic-only 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.

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 2018: US$750**)*Transactions of the AMS, Series B*: List Price US$2,750

(**Discounted price through end of 2018: US$1,400**)

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

- The Creative Commons Attribution-Noncommercial License(
**CC-BY-NC**), 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(
**CC-BY**) [NOTE: This license is mandatory for compliance with the RCUK policy(United Kingdom) and thereforerequired for any EPSRC-funded paper published under open access.]

Authors will retain copyright to their articles under both CC-BY-NC and CC-BY.

Further information on general AMS copyright policies are also available here.

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 APC-supported 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.

The AMS is currently fully compliant with existing open access policies from international research institutions, research funders, and governments including:

- RCUK (Research Councils of the United Kingdom) on open access
- OSTP (Office of Science and Technology Policy) policy memo

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.
