I really like the idea of this newsletter, "Adventures in Typography" by Robin Rendle. Anyone interested to learn things about, with and around typography should have a closer look.
A weekly love letter to the written word by Robin Rendle. Topics include: calligraphy, lettering, display type, micro type, books about fonts, type specimens, neon lights, posters, morse code, stamps, literature, web design, and books about seeds.
