The Great Gatsby - no preface 12.26.06

It appears that the edition we used to sell (probably up until 2004) of the Great Gatsby contained a preface, afterward, notes etc. A new edition came out in 2004 and we switched to selling that one. This edition contains no preface, afterward or notes. The references to these in the IG will need to be removed.

Reassure the customer that the goal is for the student to come to his or her own conclusions, so this material is not essential. The IG will be updated for 2007.
