Segment from a researcher request

[mizarchivist]

A guy has been emailing me about getting copies of some images we've scanned. They're pretty much public domain/ not unique, so no charge. He'll be using them with whatever he's putting into a Kindle version of some non-fiction/history book.

Me: "What size [for the file] do you need?"
Him: "3.6 x 4.8 inches, please."

..... Ohhh. No. No, sweetie. I knew I should have been more specific using that term "size."
