Recently I asked a friend to keep an eye out for issues of a British magazine of the 1970s / 80s. That he might encounter in charity shops or on eBay, for example. This week he mentioned to me that he noticed many of them have been scanned and torrented. I've never downloaded a torrent before but this looks like a great opportunity. So my quandary is: who could I legally pay for an equivalent resource? Many of the authors are now dead and the publisher went bankrupt.
