Hunting for books in Mountain View

I walked to Mountain View (40 minute walk from Los Altos) to buy the books recommended by Carnegie Mellon for the Masters programme. Looked in 4 book shops but could not buy a single book. Only "Extreme Programming Explained" was there in one shop but that was the 2000 edition. I need to buy the 2004 edition of the book.

Bought a map of Silicon Valley and a travel book on San Francisco Bay area. Took a bus back to Los Altos.

Took some pictures in Mountain View:
