The last price increase was in 2000. According to the site, http://a257.g.akamaitech.net/7/257/2422/01jan20071800/edocket.access.gpo.gov/2007/E7-3160.htm, NARA is proposing a price hike. This could be detrimental to many who use the records in their genealogy quest. NARA has invited interested parties to make comments by April 27, 2007, by either fax, mail or through the Federal eRulemaking Portal: http://www.regulations.gov.
While all of their prices appear to be on the launch pad, the biggest increase is scheduled for complete pension files more than 75 years old. The current price is $37, while the proposed price could be as much as $125.00.
Please voice your opinion to NARA by the deadline. In my opinion, perhaps a more modest price increase would be a better approach.
