I once wrote a program that used PHP and a programming interface known as PHP/YAZ to query the library of congress database for book information automatically.

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. -- Marcello Perathoner webmaster@gutenberg.org
