From Tom comes this pointer to the Directory of Open Access Journals, a wonderful source and resource for READABLE-WITHOUT-PAY journals in many many subject areas. What an amazing find.
From the Mt. Sinai Journal of Medicine (article on cardiac catheterization stents here) to Music Theory Online, and that's only in the "M"s. Check out the Subject Tree.
Tom is a man with a mission, and we all benefit from his determination. Not to mention his humor and impressive library of titillating images.
How I spent my summer vacation. Thanks Tom!!
