How can I tell if a book has been trimmed??? 0

Apologize if this has been discussed before, but I didn't see anything recently in the forums.  What's the best way to determine if a book has been trimmed?  Do you have to measure the book or just look for rough edges?  I struggle with the rough edges approach as there are many older books (silver age, etc.) that seem to have rough looking edges but have blue labels.  Any thoughts?

There is a permanent "sticky" thread on detecting restoration. 
 

I should count as an experienced collector, but I completely suck at detecting trimming. Old books were printed cheaply and miscuts were common. So unless it was a six year old with a pair of school scissors, I'm useless at spotting trimming.

Thanks.  I will read the thread.

Easy way to tell if a book is trimmed is to find a book from same year and roughly same month and compare the sizes.  I do this all the time and about 2 out of 3 harder to find books that are big money issues I see trimming on.
