Introductory Note: After publishing bibliographical notes on articles and books written by Bulsa authors (BULUK no 1) and a list of books and bookles edited by GILLBT (BULUK no 2), below you will find books, in which the Bulsa and their culture are mentioned. No monography on the Bulsa exists before independence day (1957) and often we can find only short hints. Of greater importance among the very early publications are Clarke (1848) and Koelle (1854) as the first sources with Buli wordlists, Cardinall (1920), Tauxier (1912) and Rattray (1932).
