DONALD WARRIN specializes in the history and literature of Portuguese and Cape Verdean immigrants in the United States. His books include Land, As Far As the Eye Can See: Portuguese in the Old West, written with Geoffrey L. Gomes, which appeared recently as Portugueses no Faroeste: Terra a Perder de Vista, published by Bertrand Editora, Lisbon. He has written as well on the participation of Portuguese from the Azores and Cape Verde islands in American whaling. So Ends This Day greatly expands upon this previous research. After retiring from the faculty at California State University East Bay, in 2003 Warrin became the first Visiting Distinguished Professor of the Hélio and Amélia Pedroso/Luso-American Foundation Endowed Chair in Portuguese Studies at the University of Massachusetts Dartmouth. He subsequently served as associate director of the Regional Oral History Office at The Bancroft Library, University of California, Berkeley; and currently continues in that program as a historian.
