Adventures in Odyssey assorted series

There are 74 and counting numbered audio Adventures in Odyssey with several none numbered collections, several book series, etc and 17 videos that break into 2 series, our library added new to the second series to separate them, lists below and series URLs.

Shouldn't the different type of AIO Adventures in Odyssey series be listed as separate series? One for audio cassette tapes, CDs, other, one for the visual VHS, DVD, other and one or more for the different book series if they don't already have a different series name?

I would say either they could be put into two series as you say: one for video and one for audio (and another for books, or whatever). OR they could be put into a single series and then separated out into different Groups within that series (one as Core and the other as Audio or Video, say). Less work that way since there are so many in that one series now. I don't think there's a standard site-preferred approach, but those are two I think would be reasonable.
