 I have introduced various old record catalogues in my previous articles (see “Old Record Catalogues” articles, Part 1, 2, 3, and 4, although they are currently written only in Japanese), and some articles also featured qutations from disc reviews and ads on Down Beat magazine back issues which I have. Actually it’s always fun and interesting to read from pages to pages, ads to ads, reviews to reviews – such magazines and newspapers of many many years ago still delivers atmosphere of that era, working like “time capsules” of when Jazz was one of the driving forces in the Popular music. Other than that, they are full of invaluable information which is very useful for discographic purpose.
