These comics were originally published by Topps Comics in the mid-90s at the height of The X-Files's popularity. The hardcover edition is well-produced; the stories themselves are a good mix of done-in-ones and multi-parters (with an overarching storyline in the background). Writer Stefan Petrucha does an excellent job replicating the witty banter of Mulder and Scully, and Charles Adlard does an excellent job on the art. The worst thing I can say about it is that occasionally Scully switches from a redhead to a blonde on the same page, and that some of the other characters are indistinguishable. Otherwise, it's great, with some truly striking imagery. This first volume collects the first nine issues of the series. This includes:
#1 Do Not Open Until X-Mas: This issue was virtually impossible to find back when it was originally published. It depicts Mulder and Scully investigating the Fatima Prophecy.
#2 The Dismemberance of Things Past: Mulder and Scully investigate a Roswell-like community.
#3: A Little Dream of Me: Mulder meets a rogue agent who claims that he can bring back Mulder's sister. This issue is notable for the first comics appearance of the Lone Gunmen.
#4-6: Firebird: This three-parter sees Mulder and Scully investigating an alien in the Southwest that is connected to the Tunguska incident.
#7: Trepanning Opera: One of the closest in tone and style to the series, with the agents pursuing a serial killer who can apparently see the future. This one has a great reference to a certain short story about a protagonist who escapes from hanging.
#8-9: Silent Cities of the Mind: This two-parter has Mulder and Scully discovering an Aztec-related lost city in Alaska.
