The library has 354 events this July (I'm doing this page in July 20160. Because of volumn, I will defer to the individual branches for their events. Go to sfpl.org, click on libraries and a drop down list of branches will appear. Select your local branch.
Check the library card application. A California drivers license is the only requirement for a library card.
This is not my list and I strongly suggest that you visit a web site prior to visiting and confirm that it is valid and accurate. To note errors to me edshuck@noevalley.com .
Each month the Rec and Park department announce a variety of events (sponsored and non sponsored).
