>>12583604>placing a sheet between each pageWhy? What would be the point of that? The notebook would double in thickness, wouldn't that weaken the pages at the spine?
besides, the notebook pages are already made of paper, so how is adding blank pages supposed to preserve anything?
The thing won't be falling apart for several decades at least, how long do you want it to last, op?
If you want to preserve the content for the long-term, your best bet is to scan the whole thing digitally and copy to a bunch of digital archives, in addition to keeping good care of the original physical notebook.
