Archivists with the D.C. Public Library are sorting through the historic artifacts that were stored at the Georgetown branch, trying to determine what can be salvaged from a three-alarm fire. The blaze destroyed the roof of the building near Wisconsin Avenue and 'R' Streets and burned many of the priceless artworks and documents. The building's Peabody Room housed files on every Georgetown home, which took researchers 20 years to compile. There were also rare maps of Civil War fortifications and a copy of the 1775-1776 Maryland Gazette newspaper that contained the Declaration of Independence as a news story.

Officials say none of the material was on microfiche or made into digital copies - and not even the Library of Congress has duplicates.

Investigators haven't determined the cause of the fire or the cost of the damage.

Meanwhile, District fire investigators believe the fire that gutted much of the Eastern Market complex was sparked by an electrical problem. The fire did an estimated $5 to $10 million damage to the building's southern and central sections. D.C. Mayor Adrian Fenty and Ward Six Councilman Tommy Wells are expected to talk about plans to restore market operations during a 10 a.m. news conference at the market site. Fenty said Monday that the 134 year-old building will be restored. Delegate Eleanor Holmes Norton said Monday that she would seek federal help to rebuild the city-owned landmark.

Residents of the Capitol Hill neighborhood have already launched a fund-raising effort to help vendors and workers displaced by the fire.
