Statistical Analysis of Copyright Registrations

linuxizer writes "I've been poking around in Penn's Library for most of my Freshman year, looking up copyright statistics. What I found is basically what many suspected all along: extending and strengthening copyright terms has little effect on actual innovation. Perhaps most fascinating is the strong 40-year upward trend in registrations which is sharply broken in 1991 with a precipitous decline. Also included are some interesting observations about the RIAA's data. The numerous graphics should be well-enough explained that you don't need to go to the data files, but they are included if needed."
