  • The Wyoming Business Council's own certification files and any certificate numbers were not retrieved.
  • Business Ready Community grant awards and Wyoming State Loan and Investment Board records were not searched.
  • Cheyenne LEADS project records were not searched.
  • the current review did not include a broad discovery sweep for Wyoming, so all Wyoming sources were found by following dataset source lists and site navigation rather than by keyword search.

  Selected records

  Selected records

  • laramiecountywy.gov and cheyennecity.org could not be reached by direct access, but were readable through an alternate access method and the linked county memo PDF was not retrieved.
