The way to access Hatch Library materials is first to log in as yourself in the portal, then look for the Hatch Library quick link. That should pass you in to the databases. If you are asked for a login again, it is your campus username (BUT NOT the email part, @baypath.edu) and your password.
Note that not all articles are available to us, so if the reason you are having trouble getting in is because you are going to a publisher website, you'd want to backtrack and look for a link to request materials through us via interlibrary loan. In ScienceDirect, you'll find a link to request a document. It comes to the librarians and we take care of the request.
