Be careful when selecting publishing channel for an article, if the publishing channel is previously unknown. The reliability of open access journals can be assessed in the same way as for traditional scientific publications. At least these should be checked:
Always watch out for predatory publishers!
Parallel publishing is a form of free accessibility, where a publication published through a publication channel is also made freely accessible in a university's institutional repository. Most universities and research institutes have digital archives. The National Library maintains Theseus (publications of universities of applied sciences) and Doria (publications of Finnish universities).
Research institutes and funding agencies also recommend or even require that research results are made freely accessible to promote research transparency, the possibility of repetition and thus increasing reliability. For example, the Academy of Finland requires that the research they fund as far as possible should be parallel published in freely accessible archives or databases.
Parallel publishing is free for the researcher and the organization, and it meets the recommendations for accessibility, visibility, and archiving in the same way as publishing in an open access journal. ROARMAP is a registry charting open access mandates and policies adopted by universities, research institutions and research funders. The Directory of Open Access Repositories, OpenDOAR, offers a list of open publication archives, among others arXiv.org.
In SHERPA/RoMEO you can check scientific journals' and publishers' copyright policies and approach to self-archiving. The service is maintained by Nottingham University. Publishers' and magazines' position on parallel publishing is shown with colour codes
ROMEO colour - Archiving policy
green - can archive pre-print and post-print or publisher's version/PDF
blue - can archive post-print (i.e. final draft post-refereeing) or publisher's version/PDF
yellow - can archive pre-print (i.e. pre-refereeing)
white - archiving not formally supported
Most publishers (78%) allow some level of parallel publishing.
