For the record, June 2, 2014:
More than three months after this database was initially published on Oct. 13, 2013, an update was made that inadvertently used incomplete information from a table that predated publication. As a result, between Jan. 24 and June 2 some responses from owners and other details were missing. The website now reflects the most up-to-date content, and The Times has noted each owner response that was affected by this data swap.
