John Gillum, the library department official overseeing the project, tells the Austin American-Statesman (http://bit.ly/11XHg38 ) that a ground-breaking ceremony is set for May 30.
The 200,000-square-foot limestone and glass building is expected to open in 2016.
It will include an atrium, a street-level cafe, "reading porches" that overlook Shoal Creek and Lady Bird Lake and a rooftop garden.
Gillum says the six-story library will be "a destination."
The library is expected to cost $120 million, including money to build it, as well as outfit it with furniture, computers and new books and library materials. Most of the money will come from a 2006, voter-approved bond package.
