The facility is expected to re-open in late October. Details may be found at http://www.archives.gov/philadelphia/press/2013/renovation.html.
I find it interesting that the Philadelphia facility is adding more computers and reducing the number of microfilm machines. I hear similar stories from libraries and archives nationwide. As further proof of the need, the last time that I was at the Family History Library in Salt Lake City, I noticed that only about one-third of the microfilm machines were in use while almost all the computers were being used at any moment. This is after the Library's managers increased the number of computers and reduced the number of microfilm machines a few years ago. Indeed, the world is changing, moving to newer technologies.
My thanks to newsletter reader Carolyn Thompson for telling me about the renovations at the National Archives and Records Administration Regional Library in Philadelphia.
