Compendium

A compendium (plural: compendia) is a concise collection of information pertaining to a body of knowledge. A compendium may summarize a larger work. In most cases the body of knowledge will concern a specific field of human interest or endeavour (for example: hydrogeology, logology, ichthyology, phytosociology or myrmecology), while a general encyclopedia can be referred to as a compendium of all human knowledge.
