I too have some drawers of cassettes (several hundred), most home recorded e.g. albums, broadcasts, live shows also some commercial releases. Busy triageing them at the moment into "really would like to save", "some interest" and "zero to little future value". "Really would like to save" is mainly unique live recordings of artists I respect - I have slowly been "leaking" these out to youtube e.g. https://www.youtube.com/watch?v=gDTbEhCWD2s, https://www.youtube.com/watch?v=kW7tF_hvUz8, https://www.youtube.com/watch?v=qskuAEG2MPk, https://www.youtube.com/watch?v=ZqtVm_PryQo, https://www.youtube.com/watch?v=5zSq2UTkiSI

- also a few radio broadcasts that nobody else seems to have (e.g. Fairport at Cropredy 1984, Mark O'Connor at Cambridge 1986, and so on...).

"Some interest" is mainly commercial things that were released only in the cassette format and/or odd tracks that would be tedious or expensive to re-purchase on CD, or now out-of-print LPs never reissued; "zero to little future value" are mostly dubs of commercially available LPs that I *could* re-purchase on CD if I really want to (but probably don't).

The "Really would like to save" batch is gradually being transferred to CD and/or wav format for safe keeping, but it is a slow task and may take the rest of a lifetime - depending on how short or long that is!! Then there are all the video tapes, which is another story for another time, most likely.
