The National Archives position on copying and scanning? They state it like this:
Self-Service Copying in a Research Room
When you are using records in a NARA research room, you can almost always make your own copies of both paper records and special media, such as film footage or photographs.
Allowable Use of Scanners
Only flatbed scanners are allowed. Automatic feeder devices on flatbed scanners are prohibited.
Equipment platens or copyboards must be the same size or larger than the record to be copied. No part of a record may overhang the platen or copyboard.
No part of the equipment may come in contact with records in a manner that causes friction, abrasion, or otherwise crushes or damages records.
Light sources must not raise the surface temperature of the record being copied.
All equipment surfaces must be clean and dry before being used with records.
On the other side of the coin, we have the Indiana Commission on Public Records, somewhat further down the food-chain in regards to customer-oriented user-friendly service.
Their policies on copying and scanning? Note these:
Indiana State Library: Manuscripts Division
"All photocopies and scans will be made by the library staff. Use of a personal scanner is prohibited." (Indiana Division Librarians verbally say digital cameras are allowed.)
Indiana State Library: Genealogy Department
(No specific policy posted-Librarians verbally say no scanners)
Indiana State Archives:
"No personal scanning or camera equipment is permitted to be used to record documents at the State Archives."
The Indiana Bicentennial is coming up fast--200 years from our statehood date--from the 19th century to the 21st century. It looks like the ICPR has a teensy way to go to reach the 21st century. Perhaps they should be sent a memo--this is the era of the internet, digital media, cellphones, satellites, cable TV, empowered informed citizenry, webinars, Wikipedia, Facebook, Twitter...need I go on. Hint to ICPR: The Museum is on the other side of the Canal!
