Look for signatures (collections of pages, folded together). Look close to the spine for signs of picrel.
When closed, you should still be able to spot a collection of upside-down arches, likely with a bit of glue between them.

>Before doing the next step, note that if it's a (solely) glued book, opening wide might cause damage.
Then open the book to the middle of a signature, and open it fairly wide. Right in the middle you should either see string (appearing & disappearing in a dotted-pattern, maybe 1-2cm each)

Will post pics of mine soon, hopefully.
