From A to Z... all the letters are on Planet typography.
Planet typography is a portal dedicated to typefaces and typography which proposes a comprehensive directory of links, a webzine which introduces the most famous contemporary type designers (in the October issue, Jonathan Hoefler, designer of Hoefler text), a typographic manual, a bookshop and a section dedicated to the freeware creation.
The site was launched in 1999 and is edited by a typo addict (but who does not work in the graphic design industry). Its target is to educate type users (all of us who have a computer) to the art of type creation and to vulgarize its unknown art.
A new version has been launched in October.
