If you would like to know more about typography, the meaning of terms used with regards to type (such as tracking, kerning, leading, x-height and more) and a little type history lesson thrown in for good measure, then check out Thinking With Type. For more in-depth discussion about type and some general “rules-of-thumb” you can check out Learn Typography and Page Layout. They have a great page that discusses some dos and don’ts of setting type.
