PASS CHRISTIAN, Mississippi (AP) -- As Hurricane Katrina approached, local historians were confident a vault filled with precious pre-Civil War pictures, maps and documents cataloguing the history of this Gulf Coast community would be safe.Hopes were high after the storm passed. The former bank building that served as the Pass Christian Historical Society headquarters washed away, but its vault still stood. Workers opened it to find wet, sopping papers -- the ruined history of a seaside town. Most of the collection including town ledgers and old newspapers is lost."Apparently, the vault did not hold back water," said Lou Rizzardi, an alderman and historical society member in the town of 6,750. "So it penetrated. Things got damaged because of water."All up and down the Mississippi Gulf Coast and into New Orleans, archivists and local historians are taking stock. They're worried about the future, but wondering also, what do they have left of their past after Katrina's 145 mph winds and a massive storm surge on August 29 splintered many communities and left others waterlogged.Many are considering whether it is wise to keep such valuable documents in disaster-prone areas.Family diaries and photographsElsewhere in Mississippi and New Orleans, archivists swooped in as soon as they could after Katrina to rescue documents, sending them in refrigerated vans to special labs for restoration.Just a few miles west of Pass Christian, the Hancock County Historical Society in Bay St. Louis fared much better with very little water damage and a vault that held, protecting thousands of documents, including family diaries and thousands of local photographs.Charles Harry Gray, the executive director, was prepared in case disaster struck. Over the years he had been making copies of all of the group's most treasured documents, including 30,000 pictures. Not one single photograph or record was lost.They are the pieces of Bay St. Louis' 306-year history that made the town of 8,230 what it is today, he said. Many of the copies were on computer disks and hard drives, others were sent to the University of Southern Mississippi, two hours north in Hattiesburg."It is imperative that you have copies in other locations because you never know what's going to happen, what the next catastrophe is going to be, and there certainly will be one," Gray said.There were no copies in Pass Christian. Rizzardi said the hope for the town's past lies with a local plumber, Billy Bourdin, who kept 3,400 vintage pictures on computer disks as a hobby.The actual photographs and his eight piles of newspaper clippings are gone, Bourdin said, but the disks survived."Stayed on the desk shelf during the storm. So far they've meant very little. Maybe they'll mean a little more now," said Bourdin, who displayed many pictures at his Bourdin Brothers plumbing shop downtown, a two-story brick building whose first floor was gutted by the storm.Rizzardi finds himself second-guessing his trust in the vault.'Don't want to come and take it from them'Perhaps the state capital at Jackson, about 170 miles to the north, would be a good place to store duplicates, he said. "Somebody off the coast that has a vault, though we would like to have them close at hand so we have access."Mingo Tingle, a preservationist with the Mississippi Department of Archives and History, says taking local historical documents away from towns for safekeeping is a touchy subject."This is their history," Tingle said. "It belongs to them. We don't want to come and take it from them. If the local historians would just make copies, send the originals to places like Jackson where we have the facilities to file that."There are archivists working all along the coast, he said, in such cities as Gulfport and Biloxi to help local historians salvage what they can."We've had people over there, talking to them, how to save their records. How to dry them out," Tingle said. "Mold grows very quickly."Mold and water damage affected thousands more documents that could be saved. Edmond Boudreaux, chairman of the Mississippi Coast Historical and Genealogical Society, climbed into the Biloxi Public Library the day after Katrina to assess the damage to the group's collection, which was housed there.While most items were safe in a vault upstairs, many items had to be freeze dried and sent away for treatment, he said."Once it's wet, you don't want it to dry out," Boudreaux said. "It will stick together. You can slowly warm it up and bring it apart while it's still moist."Greatest loss in New OrleansBoudreaux said he never thought Katrina's waters would reach the library."Nobody ever dreamed that we would have one do as much damage to the historical integrity," he said. "You grab things just as you're walking out the door, but we would have taken a lot more. We didn't know it was going to be as bad as it was."The greatest loss in New Orleans came at City Park, where experts say archives dating back to 1892 were under 6 to 7 feet of water for several weeks."Four drawers of vintage photographs from 1890 made from glassplate negatives, 50 drawers of architectural drawings, uncountable snapshots, scrapbooks," said Sally Reeves with the Louisiana Historical Society in New Orleans, ticking off the losses. "None of it was copied. There was no money."The New Orleans Notarial Archives, which hold all private-sector contracts back to the 1730s, were not harmed, she said.Boudreaux says there is joy in finding little pieces that survived the storm."It's one little victory in all the disappointments," he said. "One photograph, one document."Charles Sullivan, a history professor at Mississippi Gulf Coast Community College, said quirky examples of local history are often difficult to hold onto."The things that they have that are unique, that nobody else had them, they're gone," Sullivan said. "Nobody will ever have them again. We have already lost so much in (1969 Hurricane) Camille. All we had left of that loss was the documents and pictures and for them to be lost too is doubly disastrous."Back in Bay St. Louis, some of Gray's historical gems sit safely on shelves. There's a complete set of "War of the Rebellion: Official Records of the Union and Confederate Army" next the homemade scrapbook "History of the Bay High Parent Teacher Association," complete with black and white photographs from the 1970s.Gray said he hopes local groups will develop the technology to protect their collections by the time the next hurricane approaches."We have to close out this chapter of our lives," he said. "And put the photographs of what happened to us and our houses in the albums with the others."Copyright 2005 The Associated Press.
