After submitting your preprint to an Open Access repository of your choice, here are the tools you can use to decide which Open Access journal to submit your manuscript to:
Think. Check. Submit
Think. Check. Submit. helps researchers identify trusted journals and publishers for their research. Through a range of tools and practical resources, this international, cross-sector initiative aims to educate researchers, promote integrity, and build trust in credible research and publications. Go to thinkchecksubmit.org and follow the checkboxes.
Open Journal Matcher
Additionally, you can copy & paste the abstract of your preprint into the #OpenJournalMatcher to get a list of all the affordable (or even free of APC) journals indexed in the Directory of Open Access Journals that match the focus of your work: ojm.ocert.at
