“Clareson is one of the academic pioneers who succeeded in gaining MLA recognition for Science Fiction as an established, separate discipline in English. For that reason alone, this or any other work by him is of considerable importance. . . . The selected listing is limited to 838 entries and includes only authors published in English in America during the 60 years covered. The annotations are excellent. . . . SF is currently developing the bibliographic foundations for scholarly work and this effort is a keystone in that foundation. Eventually, there will have to be an all-inclusive bibliography for this period; until then this work will prove invaluable. Any academic library supporting a SF program should have this.”– Choice
