Empire State College created this page linking to information about Voluntary Product Accessibility Templates (VPAT™) for various library databases, showing how they conform to the Revised 508 Standards for IT accessibility. It also includes screenreader instructions for databases and database accessibility contacts.
Google Scholar is essentially a large listing of articles, with some duplication. Few articles are full-text in Google Scholar itself. (Those would come from free journal websites.) Google Scholar searches with a looser "keyword" method, not subject headings. If you have tried other databases with little success and have consulted with a librarian for search tips, Google Scholar could be useful for those "needle in a haystack" topics.
Here's a catch: Google Scholar will easily link you to full-text articles in the SUNY Adirondack Library's databases if you are using an on-campus computer to search. (Google Scholar uses IP address based authentication to know which databases are available to the searcher.) After you do a search with an on-campus computer and review the citations, click the three-bar dropdown menu on the top left > Settings > Library Links > type in SUNY Adirondack > add check mark > Save. Your searches will include full-text results from SUNY Adirondack Library databases.
