I'm new here, and new to typography in general. Though I've been interested in design for several years, I'm much more of a developer than designer but after watching a documentary about Gutenberg I've been bitten by the typography bug.
As I'm still very much in the early stages of learning about type I'd be interested in any recommendations for books or other resources I should investigate. I have just finished reading Robin Williams Non-designers design and type books which inspired me to create a design cheatsheet (using the techniques from the book) that I could have to hand to remind me of the main principles and ideas.
I have attached it to this post and I would really appreciate any feedback or criticism you may have on the overall design and the typefaces I chose along with any tips you have for improvement.
