When I shared an image of a tape-laden document last month, I was still in the process of treatment. That treatment wrapped up a few weeks ago and here are the final results:
While the results are not that aesthetically pleasing, the document is now stable. All the oxidized tape is off and the staining has been significantly reduced. I knew there were several significant losses going in, but I did not realize just how much of the center fold was gone until all of the tape was removed. Rather than attempting to infill the areas of loss with shaped pieces of toned Japanese paper, the entire sheet was encapsulated in clear polyester. This reduced the overall treatment time, while still allowing the item to be used and handled safely.
