Mayor Adrian Fenty, along with D.C. Public Library Chief Ginnie Cooper and D.C. Fire Chief Dennis Rubin, will cut the ribbon on the restored Georgetown Library this morning. The 75-year-old building, located at 3260 R Street NW, had suffered crippling fire damage in April 2007. (Officials claimed that efforts to fight the two-alarm blaze were hindered by low water pressure in hydrants around the library — the actual cause of the fire is still not completely clear.) The library had been operating out of an interim location at 3307 M Street NW until September 13. The complete restoration project, which cost $23 million, included several upgrades to the facility — a new third floor with a larger space for the Peabody Collection, an outdoor reading terrace overlooking Book Hill Park and restored woodwork. If you can’t make it over to the library this week, there is a Grand Opening Party scheduled to take place on Saturday, October 23, from 10 a.m. to 4 p.m., where you can check out the new digs.
