Merlin Data (http://www.merlindata.com/) offers a CD-ROM with listings
of property records for California.  This database permits
batch-matching.  We are interested in similar databases for other
states.  We are not interested in on-line searches or databases that
limit queries to one-at-a-time matches.  We need to match large
numbers of records.  We would prefer databases that allow downloads of
their records into our files.
