Much literature about chess endgames has been produced in the form of books and magazines. A bibliography of endgame books is below.
Many chess masters have contributed to the theory of endgames over the centuries, including Ruy López de Segura, François-André Philidor, Josef Kling and Bernhard Horwitz, Johann Berger, Alexey Troitsky, Yuri Averbakh, and Reuben Fine. Ken Thompson, Eugene Nalimov, and other computer scientists have contributed by constructing endgame tablebases.
Some endgame books are general works about many different kinds of endgames whereas others are limited to specific endgames such as rook endgames or pawnless endgames. Most books are one volume (of varying size), but there are large multi-volume works. Most books cover endgames in which the proper course of action (see list of chess terms#Optimal play) has been analyzed in detail. However, an increasing number of books are about endgame strategy, where exact analysis is not currently possible, due to the presence of more pieces. These endgame strategy books fill the gap from the end of the middlegame to where the other type of books takes over.
