Back in 1977, one of our library staff literally stapled some replacement pages into this book. It got the job done, but the results are not that ideal, as it makes it hard to read those pages and could tear the original pages they are stapled to. But this was way before my library had a Preservation department, so I can’t hold it against them!

 Nowadays in Preservation, we “tip in” replacement pages using a little bit of glue along the edge going into the book. It works great!
