definition of Wikipedia
The Dictionary of the Middle Ages is a 13-volume encyclopedia of the Middle Ages published by the American Council of Learned Societies between 1982 and 1989. It was first conceived and started in 1975 with American medieval historian Joseph Strayer of Princeton University as editor-in-chief. A "Supplement 1" was added in 2003 under the editorship of William Chester Jordan.
The encyclopedia covers over 112,000 persons, places, things and concepts of "legitimate scholarly interest" in 7,000 discrete articles in more than 8,000 pages written by over 1,800 contributing editors from academic institutions mainly in the United States but also Europe and Asia
The "upside-down-T in a circle" symbol on the spine and cover is an artistic interpretation of the T and O map, which was first described in the Etymologiae, the most influential encyclopedic work of the Middle Ages.

Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.
Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !
