The only detraction on this is the print is incredibly tiny. For me that’s fine, but my father couldn’t read it. So I purchased the desk ref edition for him and kept the pocket ref for myself. Great books, the both of them. Just keep in mind if your eyesight is a bit poorer you may want to grab the desk ref version instead.
