Encapsulation and Screw Post Binding (2)

This book required a lot of attention. The original binding was two industrial staples, which had rusted and broken away from several pages. The pages had secured in their original positions using pressure sensitive tape (scotch tape). The pages were also terribly brittle. It would have been impossible to touch this book without causing more damage to the pages.

My first step was to remove all the pressure sensitive tape. Luckily, most of the original adhesive had deteriorated, and it came off easily. Next, I collated and pulled the book. Once I had all the pages separated, I placed them between Reemay and washed them. Twice in a warm water bath, and once with magnesium bicarbonate to act as a buffer.
Even after washing/deacidifying, the paper was still to brittle to guard and resew. So, I opted for encapsulation. This would enable the pages to be handled, and help prevent further damage. I encapsulated each page in Mylar, and bound them as a screw post binding.
These are pictures of the end result.
