We get full text articles and metadata from many different sources, primarily from indexing agreements with publishers (Wiley, Karger, Thieme, Sage, BMJ, and many more) and from different open sources such as Unpaywall, PubMed, fatcat, various preprint servers, university repositories, open access journals, and more.

Apologies for the inconvenience but we can not fully list our sources because we are adding new sources and indexing agreements from publishers every single day! If we attempted a list it would shortly be out of date.
We are more than happy to give you a current and up to date list of publishers we work with and sources we ingest from if you email us (hi@scite.ai) if you need it.
You can also freely inspect our coverage of journals and publishers in our journal list https://scite.ai/journals
If we're missing a citation,article, or source, the best way to make sure we get it is to encourage the publisher to work with us! Please contact us with the citation or article that you see is missing and we will fill see if we can contact the publisher on your behalf.
If you are looking for coverage by subject area or field, again we ingest millions of articles per week so it is best if you just email us if you'd like to know or look for your self at https://scite.ai/journals
