Old Bible

I emailed the last link I gave, saying that I think I have something from the nineteenth century that is stamped 'Entered at the Stationers Hall' and has a penciled file number on it. I think I might have a missing file. What should I do? Who should I ask?

I did that on Saturday here, which is Friday there and they are open Tuesdays to Fridays (I think), so I have no idea when they'll read my email. I'll have to just wait.
