Due to the enormous size of this list, I only show events about four weeks in advance.  The master calendar will continue to show all the events I can find that are listed on each bookstore's site.
Bookstores in this list may include:  
Barnes & Noble (various Bay Area Locations)
Book Passage (Corte Madera & San Francisco)
The Booksmith (San Francisco)
Books Inc. (various Bay Area Locations)
Pegasus Books (Berkeley & Oakland) 
Hicklebee's Children's Books (San Jose)
A Great Good Place For Books (Oakland)
Kepler's Books (Menlo Park)  
Diesel, A Bookstore (Oakland) 
 
Orinda Books (Orinda) 
I am attempting to make this a one 
stop place to find book signings in the San Francisco Bay Area!  I will 
mostly focus on YA books, but I will also include some general fiction 
if I think it will be of interest.  I do not list non-fiction books (There are simply too many events of those to list).   I think this is an extensive list, 
but there is always the possibility that I missed an event (Hey, I'm 
human).  If you think there is an event that I should include, please 
leave me a note in the comments section.  Thanks.
 All  book graphics have links to GoodReads so you can check them out.
As
 always, it is a good idea to call the store a day or two before to 
confirm that the scheduled event is still on.  I have learned that these
 events change constantly.
