I am working on my collection and i notice that AOM's year field is not at the same completeness level of the web site. There is any reason for this situation? Could i complete this information in any way?
Aom.5 uses a deprecated year field that is no longer updated by anidb, it would be possible for the tcp api to send an updated version of the field based on the new start/endyear fields but that's up to the tcp api developers.
