After a long delay, Cambridge’s main library — totally remade — is set for a ribbon-cutting ceremony Oct. 29 from 5 to 7:30 p.m., including tours of the 102,000-square-foot, $90 million facility.

The news came well into Monday’s meeting of the City Council, after City Councilor Henrietta Davis asked to interrupt regular business to query Richard C. Rossi, the deputy city manager.

Services such as the loaning of books will begin about a week later, Rossi said.

The city broke ground on the project, next to Cambridge Rindge & Latin School on Broadway, in June 2005. Click here for photos and a timeline of the progress.
