The Fort Smith Main Library will be closed Aug. 9-11 for the replacement of the building s air conditioning system. But Diane Holwick, assistant director, assures patrons that the three neighborhood branch libraries will be open; due dates for anything due during the closure will be automatically extended to Aug. 15; and access to Library2Go, hoopla, Kanopy, and the library s online catalog will be limited for only a few hours on Aug. 10 when electricity is shut off at the Main Library. Internet access at the branch libraries will be limited only at this time.
