The 12,000-square-foot building, at 1917 Candler Road in Decatur, was completed in December. It replaces the 8,700-square-foot Scott Candler Library, which has been on McAfee Road for 47 years.
The dedication ceremony begins at 10 a.m.
Designed by the Sizemore Group architectural firm, the new branch is part of a mixed-use development that eventually also will include a new senior center and senior housing.
It will have a collection of 30,000 volumes, a 90-seat meeting room, special areas for children and teens, self-checkout stations, and 27 public access computers.
The new branch is among the final four new and expanded facilities funded by the 2005 parks bond fund that raised $54.5 million for the construction of five replacement facilities, four expanded and renovated libraries, and three new libraries, bringing the number of DeKalb library facilities to 25.
The bond does not provide for operations costs.
Hours of operation will be Monday and Tuesday 10 a.m. to 8 p.m. and Wednesday through Saturday 10 a.m. to 5 p.m.
