Students who use the Cambridge Public Library may have to walk a little further if a relocation plan currently gaining momentum succeeds.

The 107-year-old library is scheduled to undergo renovations through an addition to the current site of the building that would cost more than $20 million.

However, some residents have proposed a new plan that would relocate the main branch of the library to Central Square, according to the Cambridge Chronicle.

"I can imagine something remarkable in Central Square," City Councillor Henrietta A. Davis told the Chronicle. "It's the perfect destination. It would serve a broader community."

However, Davis said in an interview last night that she was not sure whether renovating the library in its current location or moving it to Central Square was a better option.

"I don't know which is best," she said. "I only know I have info on one option and only one option."

The current plan, which Library Director Susan Flannery will present to the City Council two weeks from today, would add a 55,000 square-foot wing onto the current 35,000 square-foot library, according to Jose Gomez-Ibanez, a Cambridge resident and Bok professor of urban planning and public policy in the Graduate School of Design.

In addition, the plan calls for parking spaces for more than 100 cars, said Gomez-Ibanez, who lives on Ellery Street, next to the Broadway Street library.

Davis said she thought there were two reasons why the city should consider relocating the library.

"The main library is not good for people across the city and not close enough to public transportation," she said.

The second issue was what Davis called "bringing coals to the new castle."

"In mid-Cambridge, where the library is now, you have people who have the resources people get in the library," she said. "They have books and computers at home and things in the library."

"But there are people who are not blessed with such resources," Davis continued, "and we should bring them to communities that really need them...instead of bringing the coals to the new castle."

Other Cambridge residents agreed that the issues of accessibility and use that Davis raised were significant.

"Many feel that Central Square would be more accessible to many of the people in need of basic library services," said Robert B. Boulrice, the president of the Central Square Neighborhood Coalition.
