Hundreds of free presentations and workshops for all ages are offered at branch libraries in conjunction with the Pima County Library's 2011 summer reading program. Each age-level program involves keeping track of the number of hours read, or being read to, on a game-board or online at library.pima.gov. Prizes are awarded at selected levels. The program continues through Saturday, July 23. Call 791-4010; visit any library; or visit library.pima.gov for more information.
