Litopys UPA is a series of books, produced with the aim of publishing source documents and materials relating to the history of the UPA, as well as stimulating and publishing works about the activities of the UPA and, in a more general sense, the history of Ukraine of that period. Each volume or group of volumes of Litopys UPA is devoted to a specific theme and has a separate title. Some of the volumes deal with the history of the UPA in a given period of time or in a given region - for example, in Volyn, in Halychyna, in the regions of Ukraine held by Poland and so on. Two, three, or even more volumes may be devoted to special themes, to memoirs, or to single books by individual authors dealing with particular questions.
