San Francisco is a good city for bookstores. There's the legendary independent store, City Lights, in North Beach. There are other much-loved indies such as Green Apple Books and Browser Books. There are a couple of local chains: Books, Inc., and Book Passage. There is the venerable source of fine books, Argonaut Books.
And then there is G. F. Wilkinson Books in the financial district. This picture shows the entire store. It occupies three retail display windows, which, I assume, are available because the fast-food place that occupies the ground floor of the building didn't need them.
About a year ago, Rick Wilkinson (seen above) decided to retire and it looked like the store would close. But some of his customers formed a collective and took over the store to keep it open. A similar thing happened to Borderlands recently.
And it's not just bookstores going non-profit. Sam's Grill, which had been slinging the hash at Bush and Belden Streets for 147 years closed briefly and was reopened by customers who bought it and started running it.
Apparently we're entering an age when only tech and financials can make a profit. But people gotta eat, and people gotta read.
