The OpenAIRE Guidelines for Literature Repository Managers 3.0 provide orientation for repository managers to define and implement their local data management policies according to the requirements of the OpenAIRE - Open Access Infrastructure for Research in Europe. Initially, the requirements of the OpenAIRE infrastructure and the previous versions of the OpenAIRE Guidelines were established to support and monitor the implementation of the FP7 OA pilot. However, this version of the Guidelines, according to the expansion of the aims of the OpenAIRE project and infrastructure, has a broader scope. In fact, these guidelines are intended to guide repository manager to expose to the OpenAIRE infrastructure not only EC funded publications but also other Open Access publications, regardless of their funding. So, by implementing these Guidelines, repository managers will not only be enabling authors who deposit publications in their repository to fulfill the EC Open Access requirements, and eventually also the requirements of other (national or international) funders with whom OpenAIRE cooperates, but also incorporating their publications into the OpenAIRE infrastructure for discoverability and utilizing value-added services provided by the OpenAIRE portal. According to the ongoing expansion and anticipating the merger of the DRIVER Guidelines into the context of OpenAIRE Guidelines, detailed content from the DRIVER Guidelines 2.0 was adapted and added into this version of the Guidelines. The OpenAIRE Guidelines for Literature Repository Managers 3.0 are now only a part of a set of OpenAIRE Guidelines that also includes the OpenAIRE Guidelines for Data Archive Managers and the OpenAIRE CERIF-XML profile.
