This is the official message on their site:
"As of April 2023 we have ceased to advertise our new releases in Fanfare. We have now altered our release schedule from twice a year to
every few months. Some of these releases may be reviewed in Fanfare. These are steps we must take in reducing our operation on the way to closure sometime up ahead. When that occurs, even though we will then no longer release new sets, the Music Society will continue its operation in supplying past releases from our archive. We continue to prize your interest and generous support of our endeavor."

And eventually, this time we have no Toscanini
