The library is near the border with Berkeley, in the middle of the block
south of 66th Street on the west side of Telegraph. It's between
Ashby and Alcatraz. Finding a parking
space isn't hard.
It's a little bit of a walk (10-15 minutes?) from the nearest BART stop on
Ashby. Some other stops on lines going east maybe nearly as
close.
