I was delighted to find this website Typography for Lawyers. Butterick has even written a book on this topic. His site breaks typography down into easy to understand examples for the non-typographer. This site is very useful whether you are a lawyer or not, graphic artist or not. It is easy to understand and fun to read.
Matthew Butterick got his B.A. degree from Harvard University in visual & environmental studies, also studying mathematics and letterpress printing. His work is in the permanent collection of the Houghton Library at Harvard. Butterick started his design career at the Font Bureau as a typeface designer and engineer. At the beginning of the Internet era, he moved to San Francisco and founded website design and engineering company Atomic Vision. Atomic Vision was later acquired by open-source software developer Red Hat. More recently, Butterick got a law degree from UCLA and has been practicing civil litigation in Los Angeles. While he's not the only typographer-turned-attorney in America (or even in Los Angeles), he is the only one who operates a website called Typography for Lawyers. - Font Bureau
