Compendium

A compendium (plural: compendia) is a concise, yet comprehensive compilation of a body of knowledge. A compendium may summarize a larger work. In most cases the body of knowledge will concern some delimited field of human interest or endeavour (for example, hydrogeology, logology, ichthyology, phytosociology, or myrmecology), while a "universal" encyclopedia can be referred to as a compendium of all human knowledge. It could also be referred to as a tome.
