Believe it or not, there was a time when the  San Diego Public Library was open twelve hours a day, Monday through Saturday, plus Sunday afternoon.  The librarians took only three holidays: Thankgiving Day, Christmas, and July 4th.   One of my favorite library photographs is shown here below.  Those were the days . . .

In the early 1900s, San Diegans expected and received generous public hours at the Central Library.
