Unconquerable journals resisting Open Access

Under this umbrella term, we include both the MEDLINE journals which do not offer any known open access option for their authors and strictly prohibit self-archiving in institutional repositories, as well as those which simply fail to clarify their position on this in Sherpa Romeo.

This data set is derived from a compilation of 4 sources which all have their specific licences:
