Must-read book: One book that I recently discovered is Finer Points in the Spacing & Arrangement of Type, by Geoffrey Dowding. I have an edition from 1992. It is relatively small and easy to read, and it contains all the information a designer needs to know about typography.
Game changer: Fontstand.com is easily the number one font renting service for designers this year. This app makes it really easy to quickly access typefaces. And Fontstand provides special offers for schools and students, which is even more important.
I think it will definitely change the font market, if not the world.
