One of the things I like about living in Edinburgh is that it has one of the UK’s copyright libraries, The National Library of Scotland. Copyright libraries are libraries where publishers are required to deposit a copy of whatever they publish.
Something I’ve found, however, is that the usefulness of the copyright library when you’re studying film depends somewhat upon the kind of film that you are studying: If you’re looking at cult film, more likely to be written about in fanzines than professional magazines, then you’re less likely to find the publications you are looking for, in large part because they aren’t part of the ‘official’ culture.
Much the same seems to apply to film, albeit with a much worse initial starting point on account of the historical understanding that they were ephemeral, commercial products that didn’t need to be preserved.
While all manner of stuff that I’d never dreamed of seeing 15 or 20 years ago is now available on DVD, or can be accessed via torrents of Greek VHS rips, Italian TV broadcasts or suchlike, the fact nevertheless remains that by and large it’s so much easier if your tastes are confined to the hegemonic Hollywood and European arthouse canons.
