For the notions tense and aspect I refer to Comrie (1976; 1985), Lyons (1977: esp. 689) and Pinkster (1983b: 271–86). A survey of the most recent publications may be found in Bertocchi (1980) and Pinkster (1983b). The best –though, unfortunately, not very accessible–study of aspect in Latin is Kravar (1980). See also Grassi (1967). To my mind, the best survey of the uses of the tenses is still Blase (1903). For the imperfect see Mellet (1988). Most attention continues to be devoted to the perfect and the imperfect. An extreme point of view may be found in Serbat (1975; 1976a). See also Serbat (ed.) (1980). According to him the perfect does not indicate anteriority. A good refutation is Poirier (1978). For the development of the tense system in Romance Harris (1978) is to be recommended. A monograph on the historic infinitive is Viljamaa (1983). For the participle Laughton (1964) is to be recommended.
