Draconomicon
The Draconomicon can refer to one of three sourcebooks for Dungeons & Dragons which, as the title suggests, focus on examining the Dragons of D&D. The first Draconomicon was printed for Dungeons & Dragons 3rd Edition. In Dungeons & Dragons 4th Edition, the Draconomicon was revived as a series of splatbooks; two volumes were printed, focusing first on the Chromatic Dragons and then on the Metallic Dragons. It's possible that the Catastrophic Dragons and Scourge Dragons may have had their own Draconomicon (either shared or one for each of them), but if it was planned, it was cancelled when Mearls took over as leader of D&D and slowly scrapped 4e to bring out Dungeons & Dragons 5th Edition. As a result, Catastrophic Dragons are only detailed in the Monster Manual 3 and in a pair of articles in Dragon Magazine issues #424 and #425, whilst the Scourge Dragons have never seen the light of day.
