If you want something extremely practical without knowing a thing about typography you can read:
Thinking With Type From Ellen Lupton Thinking with type teachs you the origin of typography (a little of history not to much depth on that), the basic and not so basic terms of typography like spacing : kerning, leading, indent and parts of the letters: x height, ascender, descender. Also teachs you practical things like griding, Pro Tips, and Type crimes that are like common errors that you have to avoid. If your thing is Web design also have a section dedicated to this thing. Thinking With type. I really recommend this book if you don’t know a thing about typography but you feel passion everything you see beauty posters and letters.
The Geometry Of Typea.ka.The Anatomy Of Type If you already have a little knowledge of typography as a designer, and you want to have guide of typefaces and how to use it in a given situation Geometry Of Type will be a useful book for you. As Typeworship says on his review: “The pithy descriptions describe each typeface’s origin and advise what makes each appropriate for certain scenarios and where it might fail. These are occasionally laced with a subtle humour that keeps the tone of the book warm. The great balance of written and visual explanation means the book works well as a quick reference but has a seductive way of drawing you in to read more and examine further.”
The Elements Of Typographic Style Named alse the Typographers Bible, I’ll be lying to you if I give a review about this book because I haven’t read it yet but is defenitely in my wish list. The reviews says: “Author Robert Bringhurst writes about designing with the correct typeface; striving for rhythm, proportion, and harmony; choosing and combining type; designing pages; using section heads, subheads, footnotes, and tables; applying kerning and other type adjustments to improve legibility; and adding special characters, including punctuation and diacritical marks. The Elements of Typographic Style teaches the history of and the artistic and practical perspectives on a variety of type families that are available in Europe and America today.” So it seems to be a very practical book.
