I had to dispose of 30 years' worth of magazines. I went through them, and scanned onto DVD the articles that I thought might be useful, creating an index of them as I went. Now I can find an article in the index, find the relevant disc, put in the page number, and Bingo! Current computers probably have enough capacity not to need the DVD, but it's useful to have a back-up copy. It's a monotonous job to do the scanning, but manageable if divided into logical time slots. Most heritage railways are inundated with magazines, and don't want them except for things like the sadly missed Modeller's Backtrack.
