On sale now is the fourth library edition of Hellboy, the long-running and supremely acclaimed supernatural adventure series created by Mike Mignola. Published by Dark Horse Books, the library editions present Hellboy material that was previously released as serial comic books and later paperback reprints in incredibly handsome, oversized volumes with thick, heavy paper and clothed hardcovers. In addition to the hundreds of pages of story, each Hellboy Library Edition comes with copious notes, sketches and other supplemental material by Mignola, making the books even more valuable to dedicated Hellboy fans.

ComicsAlliance has an exclusive look at some of the Mignola artwork that you can only find in Hellboy Library Edition Volume 4, and you can check that out as well as ten story pages after the jump.Collecting The Crooked Man (illustrated by Richard Corben) and The Troll Witch and Others (featuring work by Corben and P. Craig Russell), Hellboy Library Edition vol. 4 represents a major period of Mignola's work on the series, characterized by collaborations with some of comics' greatest artists and delving ever more deeply into the mythology and folklore that defines Hellboy, not to mention the psychology of Hellboy himself as he continues to wander the Earth after his split from the Bureau for Paranormal Research and Defense.

The following artwork is exclusive to ComicsAlliance and represents just a fraction of the 30 pages of supplemental material you will find in Hellboy Library Edition volume 4. Whether you're a longtime Hellboy reader or someone coming to the saga for the first time, there is no better way to read this Mike Mignola opus than in Dark Horse's library editions. You can purchase volumes 1-4 in finer comic book shops and bookstores or online from Things From Another World.
