Purdi's Book Emporium was a 23rd century business, a bookseller in San Francisco on the planet Earth in the 2280s decade, owned and run by a Troyian man named Purdi.
History and specifics[]
Purdi's sold books on disk and in "read while you sleep" editions, and also fulfilled special requests to print and bind books of paper pages. After several recommendations, Admiral James T. Kirk purchased a printed copy of Strangers from the Sky from Purdi's, at considerable expense. (TOS novel: Strangers from the Sky)
