Catalog numbers

Known catalog numbers are in the format “@@@@‐###”, where “@” is a letter and “#” is a number. The number is sequential in release date order, starting from 001. Occasionally, when a single is released before an album or EP, an “A” or “B” will be added to the end. Known variants are:

• CVRD‐###: Seems to be used for most all digital releases.
• HOLO‐###: Used for full‐length albums. As of writing, has only been used twice.
• HLEN‐###: Used for an early hololive English release, Your Mori. They seem to have stopped using this format.
• HOLOEC‐###: Used for CD releases starting late 2021? As of writing, we may be missing the first 4 releases with this number variant.
