In offset printing, the pages of a book are arranged in multiples of 32 or 16 pages per press sheet depending on the trim size. When the larger sheet is folded, the pages back up in numerical order. Each multiple of 32 or 16 is referred to as a signature. Any given book will have many signatures. For example, a 64 page book has two 32 page signatures.
