A: San Francisco, California, United States
In 1991 typographer Sumner Stone, the first director of typography at Adobe Systems, published On Stone. The Art and Use of Typography on the Personal Computer in San Francisco, California. This book, set in Stone's "Stone" family of type faces developed for Adobe and announced in March 1988, was probably the first book on typographic design for the personal computer set in a digital typeface that originated in a page description language; in this case, PostScript.
