Tools

The following tools help authors when publishing open access publications as well as when subsequently making non-open publications freely accessible, thus saving time in the process of achieving open access.

CORE

Logo of CORECORE provides a search engine for freely available publications from repositories, journals and publishers. In particular, freely available scientific articles are found, including freely available versions of publications that are originally subject to payment. The search can be carried out via a web interface, but there is also a browser extension (CORE Discovery).

Directory of Open Access Books (DOAB)

Logo of the Directory of Open Access Books (DOAB)The Directory of Open Access Books (DOAB) is a comprehensive directory of open access books. It helps authors and editors who wish to publish a monograph or collected volume as open access to find a suitable publisher. In DOAB, open access books can be filtered by subject, language and publisher, among other options.

Directory of Open Access Journals (DOAJ)

Logo of the Directory of Open Access Journals (DOAJ)The Directory of Open Access Journals (DOAJ) is a comprehensive directory of open access journals. It helps authors who wish to publish an article as open access to find a suitable open access journal. In DOAJ, open access journals can be filtered by subject and by the review process, among other options.

Dissemin

Logo of DisseminDissemin is a platform that brings together bibliographic sources and information from SHERPA/RoMEO on an intuitive interface. The service allows users to check for their own publications which of them are already freely available (whereby free availability is interpreted very broadly here, including, for example, academic social networks such as ResearchGate or Academia.edu) and which of the publications are not yet freely available and can be self-archived. For more information on self-archiving, see our Quick Guide and our page on author rights. Dissemin's checking process is particularly comprehensive if one registers with an existing ORCID account (see our information on author identification), since all publications listed there can then be checked.

OA Books Toolkit

Logo of the OA Books ToolkitThe OA Books Toolkit aims to help book authors to better understand open access book publishing. It covers specific topics related to open access books and offers brief introductions to particular aspects of open access book publishing. The toolkit also serves as a signposting tool by offering lists of referenced sources, further reading and links to definitions of key terms.

Open Access Button

Logo of Open Access ButtonOpen Access Button helps you to find freely available versions of scientific publications that are originally subject to payment. The search can be carried out via a web interface or by using the available browser extension. Extensive lists of publications can also be checked via an API.

Open Access Helper

Logo of Open Access HelperOpen Access Helper helps you to find freely available versions of scientific publications that are originally subject to payment. It uses CORE and Unpaywall to do that. Open Access Helper is available as a mobile app and desktop application (iOS and macOS only) and as a browser extension.

SHERPA/JULIET

Logo of SHERPA/JULIETSHERPA/JULIET is a database that lists the guidelines of research funding institutions regarding the requirements for publishing, open access and data archiving. It thus has a similar purpose as SHERPA/RoMEO.

SHERPA/RoMEO

Logo of SHERPA/RoMEOSHERPA/RoMEO is a database that lists the conditions and requirements for self-archiving of publishers and journals. It is therefore a valuable tool for authors who wish to make initially not freely accessible publications open access (green open access). When using SHERPA/RoMEO, however, it should be noted that the information listed there is not legally binding and therefore the original regulations relevant to a specific publication should always be checked carefully. For more information on self-archiving, see our Quick Guide and our page on author rights.

SPARC Author Addendum

Logo of SPARCThe SPARC Author Addendum offers a pre-formulated addendum for use as an appendix to publication contracts, with which authors can reserve certain rights to their publications which they would otherwise transfer to the publisher. In this way, they can, under certain circumstances, reserve the right for republication or for making the work freely accessible otherwise under specified conditions.

Unpaywall

Logo of UnpaywallUnpaywall helps you to find freely available versions of scientific publications that are originally subject to payment and thus, just as the name implies, to legally circumvent paywalls. Unpaywall offers an easy-to-install browser extension for this purpose, which automatically checks for freely available versions when visiting online articles, and indicates this with by changing the color of its icon. Extensive lists of publications can also be checked via an API.
