Hi - I am Julian from www.carmagreviews.co.nz I have produced since 2006 on line a Detailed summary of contents on NZ Automotive magazines

And from Publication date 1947 -2005 a detailed index of many of worlds car magazines from cover to cover (no just reading the contents here) I covered almost everything in magazine not only articles and tests but as also event reports (like racing); letters to the editor and anything unusual for sale - I offer a free reference service
For example I indexed June 1956 Motorsport UK to around 2001

Looks like a great site - I see lots of potential Steve
Cheers Julian
