For those like myself who are unfamiliar with (some of) these adventures, here are summaries based on info from wikipedia:
Beyond the Crystal Cave: An AD&D 1e adventure set in Greyhawk which sees the PCs hired to save a couple who eloped and fled into the Cave of Echoes. The PCs must resolve the secret of the cave to reach a magical garden where it is always summer. The adventure is noteworthy for rewarding players for resolving encounters non-violently.
Expedition to the Barrier Peaks: An AD&D 1e adventure written by Gary Gygax himself. In this adventure, the PCs explore a mysterious spaceship that crashed in Greyhawk's Barrier Peaks mountain range. The ship is filled with robots, laser guns, power armor, and all manner of strange creatures (including vegepygmies and a froghemoth). The adventure also involves collecting colored access cards to open restricted areas and the like.
Pharaoh: An AD&D 1e adventure written by the Hickmans of Ravenloft and Dragonlance fame. This one sees the PCs exiled into a desert after being falsely accused of a crime. They end up encountering the spirit of a dead Egyptian-style pharaoh who implores them to break into his supposedly thief-proof pyramid tomb and steal some things that will enable him to find eternal rest or something.
The Lost Caverns of Tsojcanth: Another of Gary Gygax's AD&D 1e Greyhawk modules. This one sees the PCs as treasure hunters seeking the wealth of the archmage Iggwilv. During their search, they encounter a vampire.
The Lost City: This is a Basic D&D adventure written by Tom Moldvay. The PCs get lost in a sandstorm and discover the lost city of Cynidicea, where the inhabitants are degenerate drug addicts. The PCs explore a pyramid and fight an evil monster.
When a Star Falls: An AD&D 1e module in which the PCs search for a fallen star in the moors. They encounter svirfneblin and derro as they seek to give the star to its rightful owner.
