Usually two pages were omitted, sometimes even three to four pages for the double-featured reprints. On November 1980, the page count was raised to 23 pages. Otherwise, wait till the Essential Series catches up. By Reprint Titles Lance Visser supplied me with the original list of reprint titles. I divided the information into smaller files for easier access.
Any unlisted title is in the Miscellaneous section.
I'm still working on many recent titles. 1-6 Books Marvel has released various reprint books over the years. Many of the older ones do not list the original comics. I don't follow comics that closely anymore, so this section is probably the least complete. Since Marvel releases tons of new trade paperbacks every year, any new information would always be appreciated.
