Interesting interview with David Walls, now of the GPO and formerly of Yale University, in today's Washington Post. Walls has joined the GPO as its first preservation librarian. He will oversee, according to The Post, "the transition to digital archiving." According to Walls, the GPO is updating the www.fdsys.gov system we previewed in last week's post and building a more robust server for its collections. Read the full interview here.
