I believe Alien appendix project is intended for video footage only. If there is an interest for CD-Rom compilation of printed promo materials and news articles a new thread should be opened so this one stays on track...
A few years ago UK's Channel 5 had a TV special "Greatest ever scary movies" with a video segment on Alien that topped#the list. Does anyone has that show (or any other in the series for that matter)? http://www2.five.tv/programmes/greatestevermovies/countdown/?list=2
