I'm going through the text:

Linear Operator Theory in Engineering and Science by Naylor and Sell, 1982, Springer.

George Sell passed away in 2015. I bought a used copy and I think it was even George Sell's copy since his name is scratched on the edge of the pages. He must not have liked page 285 / 286 because half of it is ripped out of the book.

I'd like to recover these two pages. If anyone has this reference, could you use snap a picture of these pages and send them my way?

Sorry to bother - I would appreciate the help.
