special CDs
These are the non-musical soundtrack CDs that were released. This includes the Eternal Edition CDs and the Ongaku Shuu/Best Soundtrack CDs.

DVD box sets
These are the DVD box sets of musicals that have been released. They came with bonus material not available anywhere else.

omake videos
These videos contain special footage from the musicals. Originally, they were included on the Laser Disc's of the musicals. After briefly being sold as separate videos, they now come with the pre-order VHS's and on the DVDs. They typically show senshuuraku and behind-the-scenes footage. For the most part, the DVD and VHS omake versions are different.

official guide videos
These videos were only made a handful of times. Sold at the musicals themselves, they contained clips from the Fan Kansha Event, rehearsal, and usually photo shoots. They also had brief interviews with cast members.

special videos
These are special videos. This section includes TV specials, the Ongaku Shuu videos, the 500th Performance Commemorative video, and the Otomodachi Special Video. There are probably more than what is listed here, but I have listed everything I have information on.

fan kansha events
These are events held as a thank you to the fans and in promotion of almost every show since 1998. They introduce new cast members and basically allow the cast members to act like idiots. This section also includes the Special Live that was held for 1997 Stars Kaiteiban and the Musical Tokubetsu Senkou Event held for 1997 Eien Densetsu.

all specials
This has all of the special events and videos listed, not including DVD set bonuses or CDs.
