Comment 5 for bug 128394

deduping and frbr-izing are two different things:

1) deduping: bringing together records for copies of the same edition of
the same book. we do this when new sources (e.g. new libraries) are
added to the database.

2) frbr-izing: bringing together records for different editions of the
same book.

Note that many books are only issued in one edition; frbr-izing affects
a small but very visible part of the bibliographic universe (about 5% is
the estimate). It covers popular works like Shakespeare and Mark Twain;
it should also bring together re-printings and translations with the
original work. think of it as a cluster of books with approximately the
same text, although having been published at different times by
different publishers.
