Granted, but how do you identify the book? We have no ISBN or similar 
key into the LoC database.

The LoC database contains a record for every copy of book they hold, 
which could be many hundreds for a popular work. And copies acquired in 
say 1950 are often cataloged very differently from copies acquired in 2000.

If we just had some sort of unique key into the LoC database, 
`borrowing' the data would be a child's play.
