Disclaimer: This page is mainly intended for my own use, and inclusion or otherwise of a journal does not give indication what I think about the quality of the said journal. Most journals useful to group theory will probably get on to these pages eventually. Also, I have no idea whether the IDEALibrary pages will work for you. You or your institution may or may not have the right to access certain of these sites. In fact, I suspect that most of the JSTOR ones won't work for you unless you happen to be from Birmingham.
