YAPP Binding
A limp bound book where fore edges of the front and rear covers extend beyond the front and back of the book to
fold over the of the textblock. Named for the 19th Century British book
binder William Yapp who introduced the technique for pocket sized
Bibles. This form of binding is still quite common for contemporary
Bibles and has been adopted for some other limp bound volumes.
Yapp
bindings can be sometimes divided into full yapp and partial yapp. A
partial yapp binding has the front and rear material extending
partially, but not fully, over the textblock. A full yapp binding would
have the extended material covering the textblock edges entirely,
possibly overlapping each other.
