I try everything to create a sign that work for the enchant book. I try the numeral id, The name of the book, and still dont want to works.
I wen to a shop from another guys from the serve he put only 3 differents books Silk Touch, Mending and looting 3 and the name of the object are enchant book#1x, Enchant Book#g and enchant book#m but when i look for that on the internet i dont find id of those kind.
And i really want to open my shop in the server but im not going to open my shop if i cant sell all kind of books

If you want to find the ID to use for a chest shop sign hold the enchanted book you want to sell and do /iteminfo.
