Sorry I wasn't clearer, Lee.  I take it as implicit given that reuse of the
data is an important goal for Open Library and the current state of affairs
doesn't make this possible.

I guess our analyses differ, although I admit I've only given it a cursory
look.  There *is* a lot of data, but much it was imported in big chunks and
the analysis only needs to be done once per source/import.  There's also a
lot of provenance information -- you've probably seen the page edit
histories and the links to the original MARC records at the bottom of pages.

 In the worst case, starting from scratch is an option.  In either case
though, the longer we delay, the worse the problem becomes.

My advice for those who want to ...


I wouldn't consider giving legal advice to people who aren't clients, but I
do invite anyone who's interested in helping to solve the problem to work
with me.
