The Middle Georgia Regional Library will be closed later this week as it upgrades its catalog system.

Libraries will close beginning at 6 p.m. Thursday, and the closings will continue through Saturday, according to a news release.

The Georgia Public Library Service is upgrading its PINES catalog, used at more than 275 libraries across the state. PINES, short for Public Information Network for Electronic Services, provides residents a shared catalog of almost 10 million items.

“We hope that PINES library cardholders will find this to be a more modern and more user-friendly interface,” Elizabeth McKinney, the PINES program director, said in the statement. “This upgrade will bring many improvements and new features to the PINES catalog, chief among them improved compatibility with most mobile devices and with more web browsers, including the most recent versions of Internet Explorer and Safari.”

Pages should load faster with fewer display problems. Navigation from within the catalog back to initial search results and to the new search page will also be easier following the upgrade.

More improvements, including a dedicated PINES catalog for children, are in the works and will be added to the service in the near future.

The Houston County Public Library System will be open but may have limited services available.
