Shelving Locations in A/V

Every three weeks I work at the A/V circ desk... until I hire an assistant anyway (note to self: hire assistant). The first time I worked over there, I was astounded by how many genres and shelving locations there are in that place. Each of these has a corresponding colored dot on the spine so that staff will know what shelf an item should go on.

The following are what I can remember as I walk through the department in my head. There may be more.
Anime
Action
Drama
Comedy
Sci-Fi/Horror
Musicals
Foreign
Adult Non-fiction
Children's Non-fiction
Children's Musicals
Focus on the Family
Hallmark Movies
Television Shows
Adult Christmas/Holiday (permanent)
Children's Christmas/Holiday (permanent)
Family DVD Collection (feature length)
Children's DVD Collection (30 min cartoons, etc.)
New (1 week)
New (3 day - no holds)
"Faith-based" (permanent display)
"Oldies but Goodies" (temporary display)
"Out of This World" (temporary display)
"New TV Shows" (Permanent display)

*all of the displays share the shelving location of AV-DISPLAY but are in different places around the department. 

Blu-rays are stickered with the appropriate collection color but they are all located in one place instead of being inter-filed. We do still have some VHS copies and they are inter-filed and I've been given no logical explanation for why the blu-rays aren't. There are also music CDs, audiobooks on cassette & on CD, playaways, and Wii software.    

Do kids really care whether a DVD is a movie, episodes from a show, or a musical? Probably not. I think the staff has just put way too much thought into things.
