The Orange County Library System has announced that it will close all 16 book drop locations at its branches starting Tuesday, April 7.

Library customers are instructed to return their books by Monday, April 6 or to hold their materials and return them when the library system reopens to the public. OCLS has extended all due dates for checked-out materials from May 1 to June 1 and all library fines will be suspended through this period of time.

Library cardholders can still make use of the system’s free online classes.
