Anyway, the Google result I get reads (with links omitted):
Scans of print journals, with 10 major math journals (requires subscription).
www.jstor.org/ - Similar pages - Note this
Does Google know I'm interested in math, or does it say this to everybody?
As it turns out, I was in fact looking for an article from the Bulletin of the American Mathematical Society, so telling me there were math journals in there worked out well for them.
