How can I find out whether a journal charges article processing fees (APCs)?
You can find this information in two ways:
- Go to the Advanced Search page, select 'Journals' from the 'Journals vs Articles' facet and expand the 'Article Processing Charges (APCs)' facet. By selecting 'No', you will retrieve a list of all the journals where the publisher has told us that they do not charge authors anything at all.WARNING: read this blog post about the APC data in DOAJ.
- APC information is displayed under each journal in search results and under the 'Publication Charges' section on a journal's home page. For example: https://doaj.org/toc/2193-6544
