Q. What tools do you recommend for finding open access articles?

If you find paywalled content on the web that Harvard Library does not have a subscription to, consider using the Unpaywall browser extension to check if an open access version is available elsewhere.

You can also try Lean Library, which will check for open access versions as well as Harvard Library-subscribed content.

If you would like to search in dedicated open access databases, try the following:

• Directory of Open Access Journals (DOAJ)
• Directory of Open Access Books (DOAB).
