FYI - the Pedro Cervantes book is still free in the US.
I don't read or speak Spanish, and I brought the Cervantes book largely because I wanted to look at more of his artwork. The book does include a timeline and an essay. The photos of his works are quite good, and with a price of zip,well worth it.
Circles of Delight - is, sadly, no longer free. Shepherd is better known for his children's version of various fables and fairy tales. This book is a look at the carousels in San Fran. The history of the carousels is short, but the photos are beautiful. I love that he paid attention to areas of the actual structure as well as the mounts.
