Identifying HathiTrust volume IDs suitable for inclusion in a corpus
of images for identifying sheet music.

Order to run the scripts:

1. To get a fresh HathiTrust tab-delimited metadata dump
   (for the time of writing: March 2019)


./HATHI-GET-TAB-DELIM-DUMP.sh

2. To winnow the file down to a more manageable size
   (just the columns we're interested in)

./HATHI-EXTRACT-FORMAT.sh

3. To generate a list of Music Notation entries that are in the public
   domain, and not-scanned by Google (so called 'open-open'):


./HATHI-EXTRACT-PD-NON-GOOGLE.sh
