A few years ago I asked for a list of Marvel Graphic Novels from the board members and I too was given the list of 75 as well as the Epic comics releases (Epic was a creator-owned/mature imprint from Marvel). The list is available on the silverbulletcomics.com website. If I recall it had an error; it listed Wolverine Bloodlust as a Graphic Novel when it was in fact a slightly smaller Graphic Album (as they were called back in the day). Wolverine Bloody Choices was in fact a Graphic Novel released in 1991 and re-released as a Bookshelf-format softcover (as Graphic Albums came to be known by) in 1994 without the awesome Joe Jusko cover. The list of Marvel and Epic Graphic Novels makes no mention of the very-oversized hardcover Epic release Elektra Lives Again which is an oversight but the list does make an effort to collate all the releases together. I hope that helps.
