The Perry-Castañeda Library changed its weekend hours, opening an hour earlier on Sunday and an hour later on Saturday, to meet student demands.

The library will now open at 10 a.m. rather than 9 a.m. on Saturdays and 11 a.m. instead of noon on Sundays. The new weekend hours will go into effect this Saturday, Jan. 28.

Travis Willmann, communications officer for UT Libraries, said the PCL is extending its Sunday hours because students tend to spend more time there on Sundays than Saturdays.

“It’s my understanding from the people who study the patterns here that there was a desire for the building to be open an hour earlier on Sunday, and usage on Saturday wasn’t as heavy as on Sunday,” Willmann said. “They’re going to study the new patterns that emerge from the new hours and make changes as necessary, or keep things the same if it’s working out.”

Joe Dobbs, head of user services for UT Libraries, said in order to extend the Sunday hours, the Saturday hours need to be shortened to prevent increases in expenditure. To ensure the effectiveness of the hour change, Dobbs said the library will continue to monitor available data.

“We’ve had people waiting to come in on Sundays, so we hope that there aren’t big crowds waiting any longer,” Dobbs said. “We’re going to try to look at things such as gate count, and computer logins to try to see if it was a good decision to make. We’re looking to be able to address demands as much as we can.”

Mathematics senior Fahran Kamili said he spends more than 10 hours in the library almost every day and is pleased to hear about the new opening times.

“I’m actually pretty happy to hear that PCL will be opened before noon on Sunday,” Kamili said. “On Sunday, I wake up kind of early, and I’m the kind of person who can’t really work at home, so the earlier the PCL opens, the better for me. But in the grand scheme of things, an hour, it’s not that much of a change.”

The PCL is open 24 hours a day Monday through Thursday and closes at 11 p.m. on Fridays and Saturdays.
