The Brooks/Rust volumes (the cornerstone for Columbia data at DAHR) do not include the trial/personal/special matrix blocks. They encompass only the "general purpose" blocks for 10- and 12-inch masters recorded in the US. Some matrix numbers from other series has been added as discs have been digitised.
