Design evolution:
1. Front cover with a blue frame on left mentionning World Music Network. (This is not an OBI but printed on cover) 1994 to 1998
2. No more left frame around 1999 to?
3. Similar as 2 but with a banner "The rough guide to..." on top right from cover, around ?
4. Back cover changed with all credits placed at bottom instead of right frame
From RGNET 1145 used around 2005-2006
5. New orange logo on front cover used from 2006 to ...
TBC for the changes after those dates
Around 2007 it seems 3 versions could exists with same front cover, diff being on back with: Barcode starting by 6, Barcode starting by 9 and one with the 2 barcodes.
