My college librarian set me up with an account on a platform called Athens so I can access journals at home. This may not be possible everywhere, but it's certainly worth exploring. Athens seems to link together several resources, but JSTOR and Oxford Music Online are all I've used. I only have access to certain fields on JSTOR (music and Irish studies, mainly), but I would assume this is because that's what my college teaches; other institutions may provide different accesses.
