This thread is a couple of years old, but I just started working with the
British Library 19th Century Books digital collection for the Git-Lit
project <https://github.com/Git-Lit/git-lit>. One of the first things I've
been working on is cleaning and enriching the metadata which may be of
interest to anyone else working with it.
Lars - If you're interested, I can provide you with a list of a few hundred
volumes in Nordic languages. One of the things that I did was run a pair
of language detectors over all the title data, so I've got a reasonable
guess at a language even for those editions which weren't coded in the MARC
record (plus found a couple hundred coded with the wrong language).
Sadly, although the British Library is mounting a big multi-stop road show
to try to get people to make more use of their digital collections, they
don't actually answer their email, so I'm kind of patching this together by
trial and error, but hopefully there will be a much more useful set of
metadata at the end of it.
