There was, as there was with Buster, a "Comic Library" series for Whizzer and Chips. This format was different from other Comic Libraries in that two issues were on sale at once and one was a 'Whizzer' comic and the other a 'Chips'.
I've had four or five of these comics for some time now and for a while have been trying to find out just how many of them there were, a fruitless task with which an answer could not be found in the comics or by anybody I contacted and asked.
However, there is light at the end of the tunnel and Kid over at his blog 'Crivens! Comicbooks, Cartoons & Classic Collectables!' revealed there to be fourteen, and accompanied this fact with a complete cover gallery.
So, if you didn't see the post here they are - all fourteen smashing covers!
