Omar: We normally include dates related to recordings if available, usually printed on the label itself as a year of release. Other specific dates may be included in the Notes section, added by the staff. Unfortunately, the information is not consistent and not readily available in many cases.
Sorry we could not help. Thanks for your interest in our collection.
