Lawyer/typographer Matthew Butterick created this tight and tidy shareware/donationware online book, which covers most of the basics of typeset punctuation, text formatting, and fundamental page layout principles. If you find yourself having to make a published document but do not have typeset or layout experience, this book will quickly get you familiar with the fundamentals. It’s also a good resource for choosing and purchasing fonts from a pre-curated selection (including some of the author’s own designs).
