Re: Gloy is NOT PVA

According to Arthur Johnson in his book "The Repair of Cloth Bindings: A
Manual" published by the Oak Knoll Press and The British Library in 2002
(page 11), PVA was developed in Germany in 1912 by a Dr Klatte, but it was
not in general use as an adhesive for packaging and bookbinding until the
middle of the 20th century.
