Is 'gluing' considered restoration?

Mark Zaid (Owner of Esquire Comics) gives expert video advice on: How does restoration affect a comic book's price?; Should I use tape to repair my comic books?; What is comic book 'color touching'? and more...

Gluing is typically considered restoration and is something that is certainly not advocated. For certain types of comic books like Golden Age comic books, you can have a slight amount of glue on a comic book that is not considered restoration, though typically it should still be disclosed that the presence of the glue is there. But this is not a restoration method that is typically suggested in order to use, to repair a comic book.
