In November 2007, UBC Library sent a single DVD containing more than four million bibliographic records to Backstage Library Works. The company used a series of automated programs to resolve conflicts over name headings and series titles, update subject headings, and eliminate obsolete codes and fields. Reloading of the sparkling new data began in early January with the assistance of Ex Libris Group, a library automation firm. The records were reloaded into theLibrary’s catalogue in about four and a half days. The work continues, however. Stray names and subject terms that escaped the net of the automated programs are being cleaned up by staff, and catalogue maintenance will be ongoing.
