When you are obtaining a "copy" of a document or record, are you getting an "image copy" which usually means a digital copy or a photocopy, a transcription which usually means someone handcopied or typed up the whole document, or an extract which copies relevant parts of the document?
The three obviously are not the same and if you have an extract or a transcription and things are not clear you might want to obtain an image copy if at all possible.
This is a topic we occasionally visit in Casefile Clues in more depth than we can here in a tip.
