Managing Author Processing Charges (APCs)
Author processing charges are on the rise and with recent changes to the NIH Public Access Policy, authors are frequently having to pay unexpected or exorbitant fees. There are resources, however, that you can use to find an affordable journal. This page also details what to do if you are asked to pay an open access fee to comply with the NIH Public Access Policy.
Funded Research
For funded research, prevention is better than cure. Make sure you are aware of your journal's open access policy before submitting to ensure your paper will not be subject to an embargo period, which violates the NIH Public Access Policy. To do this, look up the journal in Open Policy Finder.
Or, go to the journal's website and look for the "For Authors" section. Look for the words "fully open access" and make sure there is no mention of APCs. Or, see if a diamond open access policy is mentioned; this type of publishing model has no fees for its authors.
If your paper has already been accepted, we have outlined your options for managing APCs.

You can also look up specific journals by title in the Directory of Open Access Journals (DOAJ). The APC fees will be noted:

Non-NIH Funded Research
If your research is not NIH funded (or funded by another inapplicable funder) and one of the authors has a Harvard affiliation, you can look into depositing your article into Harvard’s institutional open access repository DASH, and requesting an open access waiver for the article. Harvard explains: "If your article is subject to the NIH Public Access Policy, your obligations under that Policy cannot be waived. The same may be true of open-access policies at other funding agencies." Always check first with your funder or look up your funder's requirements in Open Policy Finder.
I'm on the Hook for a Fee!
The resources above can be used to find an affordable open access journal. But perhaps you already signed an agreement with a publisher and are now facing a fee resulting from changes to the NIH Public Access Policy.
If this is the case for you, you have a few options:
