DragonLance Adventures provides additional campaign resource material for Tracy Hickman's DragonLance Campaign and world of Krynn, as well as information on classes, races, spells, and artifacts.

Dungeoneer's Survival Guide and Wilderness Survival Guide flesh out the worlds of the Underdark and the Great Outdoors, respectively.  Both present some genuinely valuable and interesting info, but deal with both subjects in too much detail for all but the hard-core gamer.  Both were also offered in shrinkwrapped "Limited Editions", which contained modules Dark & Hidden Ways and Wild Things respectively.

Fiend Folio is TSR UK's sequel to the Monster Manual, and is mostly a compilation of monsters previously published / submitted to White Dwarf magazine's "Fiend Factory" feature.  Originally intended to be released in November 1979 (and so dated on the preface page!), production was delayed for more than two years due to "contractual reasons".  Apparently, the manual was to be released as a Games Workshop product (licensed by TSR), but when TSR failed to merge with Games Workshop -- instead, opening the TSR UK division -- Games Workshop reportedly stalled production on the manual for as long as possible.  (Thanks to Ciro Alessandro Sacco for this info).  It was pre-released, in final form, at the GamesFair 1981 convention in the UK.  (Thanks to Adam Shultz for this info).  Estimates place the total number of Fiend Folios sold at 190,000.

Forgotten Realms Adventures, like Greyhawk Adventures, provides supplemental information to the Forgotten Realms Campaign setting.  Besides offering additional background material, spells, etc, it also serves to update this 1st Edition AD&D campaign to 2nd Edition AD&D conventions.

Greyhawk Adventures takes over where the World of Greyhawk Campaign set left off, describing in depth many additional features of the Greyhawk campaign.  It bears a "Compatible with AD&D 2nd Edition" starburst, although it does not have the 2nd Edition logo (it was published in 1988, just prior to 2nd Edition AD&D being released).

Manual of the Planes covers rules and locations for extra-planar campaigns.  It is supported by a single module, OP1 Tales of the Outer Planes.

Monster Manual II is (surprise) the sequel to the Monster Manual.  Written by the same person (Gygax), in exactly the same format.  Published in 1983, the Monster Manual II heralded the re-design of all the AD&D manuals to this style (though Fiend Folio was not reprinted after roughly 1982, so it escaped the redesign).

Oriental Adventures introduces a Far-Eastern campaign setting, replete with ninjas and samurai.

Unearthed Arcana is a rules expansion from Gary Gygax, adding new character classes (Barbarian, Acrobat, Cavalier, etc), as well as new spells, races, and magic items.  Unfortunately, many players complained that the new character classes were too powerful.  An errata article was published in Dragon #103, and this article stated that the changes would be incorporated into later prints, but this revision never transpired (thanks to Michael Deaton and Richard Graves for this info).

Printing Information

While the Dungeoneer's Survival Guide and Wilderness Survival Guide were released in "Limited Editions", the hardbacks are identical to the stand-alone versions, with the exception that the bar codes on the rear covers of the hardback books have been crossed out with a black "x", to prevent them from being scanned and sold separately from the booklets.  Thanks to Devon Hibbs and Paul Tremiti for this info.
