  OCLCs expert community (modeled on Wikipedia)
• Interest and motivation from WorldCat Local pilot
  sites that want to use WorldCat Local as their
  database of record

Expert Community Experiment

• Allows member libraries with full-level
  Cataloging authos to make additions and changes
  to almost all fields in almost all records
• PCC records (both BIBCO and CONSER) are excluded
• LC records not coded as PCC are included
• As with Enhance, the first rule will be
• Do no harm!
