A section for ‘The changes made to the Original Trilogy films over the years…’ - containing many sources of information on those numerous changes - has been added to the Index.
doubleofive’s insightful and comprehensive Complete Comparison of Special Edition Visual Changes thread, in the Theatrical Cuts vs. Subsequent Releases section of the site, contains links to many differing sources of information on the changes - as well as being the main reference point and discussion thread on the numerous changes.
As ever, please post any ideas or suggestions for additional topics or threads for inclusion here - thank you.
