One of my photos on Flickr is included in the 4th edition of the Schmap New York Guide. Look for the listing for Strand Books to show up (in the little widget shown here) or in the list (using the direct link) - my offering shows a few dozen inches of the 18 miles of shelves.
I was captured by the analogy between travel in outer space and travel in the mind through books.
On my latest trip there, incidentally, I didn't buy any books from the section depicted, opting instead for some history, finance, and humor. It would be hard for me to imagine spending any length of time in there, however, and emerging empty-handed.
