Elmers glue is PVA (PVAC) based-but has lots of other stuff (tackifiers and solvents), and has a pH of 5 (meaning it is acidic).For book binding, I would definitely recommend using a pH neutral PVA based glue that is specific to book binding.The acid in Elmers has a nice way of breaking down the cellulose in paper over time, and who knows what the other ingredients might do.
