When we were planning to publish music CDs, I tried to keep in mind that (since all the decisions were in our hands) it was a chance to think freshly and not – or not necessarily – use the reigning model of a plastic jewel case with printed ‘inlay’ sheet and booklet. I thought it would be good to try to do without plastic. It might cost a bit more money, but at least we could make a nice thing: more friendly than the jewel-case model, and perhaps more economic-elegant in its materials. This seemed important in the light of the burning question of ‘why make CDs anyway, why not just issue sound files for downloading?’ If you offer a pleasant and desirable thing, with material qualities that can never be downloaded, then it can be worth the effort and the cost of still publishing physical objects. The same set of thoughts applies, of course, to printed books and e-books.
