If you need to learn the JIF (Journal Impact Factor) or ranking of a journal, Journal Citation Reports is the place to start. Cabell's will give additional information (acceptance rate, estimated time for review and publication) about some journals in a limited number of fields of study. If you can't find information about the journal you are interested in, contact your subject librarian.
LSU Libraries can also help you learn more about author's rights and offers limited support for Open Access publishing. We also host LSU Digital Commons, LSU's institutional repository (IR).
