A&A Subscribe-to-Open FAQs

Why is A&A transitioning to open access?

Since its launch in 1969, A&A has been publishing pioneering, peer reviewed scientific content. The transition to open access will expand access to its high-quality research to a worldwide audience – furthering the field of astronomy and astrophysics in the interests of advancing open science and serving our community.

What is Subscribe-to-Open (S2O)?

  • Subscribe-to-Open (S2O) is a subscription open access model that relies on library contributions to make content open access for the benefit of the research community.
  • If subscriptions are not renewed, content remains behind the paywall and only subscribers have access.

Why should I continue to subscribe under a S2O model?

  • The only way to guarantee access for your researchers to A&A is to subscribe.
  • If support is insufficient because institutions decide to cancel their subscription or delay their subscription payments significantly, the content from that year will be published behind a paywall, and only the subscribers will still have access.
  • Your current subscription payment will show your commitment to the long-term sustainability of open access.
  • Renewal is annual, using current subscription workflows and channels.
  • Publishing a high-quality journal like A&A has a cost. EDP Sciences relies on subscription income to publish the journal. Only if publications expenses are covered can the content be made open access.

Are there charges to publish in A&A?

If A&A is converted to open access under the S2O model, everyone will have access to the content. In addition, there will be no charges for authors from A&A member countries to publish in A&A. A moderate fee otherwise known as “page charges” will be charged to authors from non-member countries to cover editorial costs.

If subscription income is not sufficient and A&A is not published in open access, authors wishing or required to publish in open access can pay an APC to have their article published in open access. See https://www.aanda.org/for-authors/author-information/open-access for more information.

What are the revenues used for?

A&A is a community journal sponsored by a board of member countries. While subscriptions fund the publishing costs of the journal, the editorial costs are funded both by the contributions from member countries, and the page charges for authors of non-member countries.

This division of costs between authors and readers makes it possible to offer low subscription prices, while at the same time removing barriers to publishing for authors from A&A sponsoring countries, and allowing authors from non-sponsoring countries to publish for a modest charge.

If the S2O model is successful, editorial costs will continue to be funded by A&A member contributions and page charges, while subscriptions will be used to cover the open access publication of the journal. Authors from sponsoring countries can therefore publish in open access free of charge, while authors from other countries remain liable for page charges to fund the editorial process of their article (note: page charges are paid to A&A directly and not to the publisher).

I can share my work on arXiv so why should I publish in A&A?

Preprint servers such as arXiv play a vital role in bringing research into the astronomy and astrophysics communities as quickly as possible. However, content uploaded to this service has not undergone rigorous peer review and the editorial oversight offered by a professional publisher such as EDP Sciences. In addition, preprints don’t offer the content selection and curation processes that make a scholarly journal a reliable and trusted addition to library collections.

In summary, publishing your article in A&A increases the value and impact of your work by making your article more trustworthy, easier to find, read, and cite, whilst ensuring that the version of record is preserved in perpetuity.

Will A&A be compliant with open access requirements of institutional or funder mandates?

If A&A receives the subscription renewals required year after year and therefore moves to a fully open access model then it will be fully compliant with funder mandates such as Plan S.

What happens if my institution or others don’t renew?

If support is insufficient e.g. because institutions decide to cancel their subscription or delay their subscription payments significantly, the content from that year will be published behind a paywall, and only the subscribers will still have access.

What will be made open access and when?

If all subscription renewals have been received, A&A will publish its newly accepted content open access, from that time.

The opening of each year’s content is contingent on sufficient participation from library customers.

What license applies to the Subscribe-to-Open content?

A&A authors whose articles are accepted, will be asked to sign a Creative Commons CC-BY 4.0 licence on acceptance of their article.
