This week the Friends of the SF Public Library are holding one of their twice yearly used book sales at Fort Mason. It's not really the place to go if you are looking for a particular book, but browsing can be fun, &, with prices topping out at $3, there's not much risk.
My strategy is to walk along the tables until something speaks to me, like this technical manual about regular expressions, in Polish.
The exception to the $3 maximum is the section for rare & collectible books, which has some amazing items. Above is a page from Street Types of Great American Cities (1896), which claims to be edifying & whose manner is exquisitely condescending, cynical, sexist & racist.
Even after examining the contents, I had no idea what was going on here.
I also have no idea what the "I" & "A" stand for here. It probably covers anyone above the age of puberty.
The Big Book Sale continues through Sunday, when everything goes for a dollar. On Wednesday afternoon the majority of customers were buying in bulk & required shopping carts, so be prepared for long checkout lines.
§ The Big Book Sale September 21 - 25, 2016 / 10 AM - 6 PM Fort Mason Center's Festival Pavilion Hardcovers: $3 / Paperbacks: $2 / Children's Books: $1 / All Media: $1 All items will be $1 on Sunday, September 25th.
