My answer is about like Sandra Basgall's earlier answer. The "Times" and "Variety" reviews are useful if available. I also depend on other sources readily available in the United States. Most useful, I think, are the contemporaneous reviews published in the periodicals cited in the biblio- graphic volumes "The Readers Guide." For me the whole point to the exercise is to get a sense of what people were exposed at the time the films were released and "Readers Guide," by definition of their mission, catalogs mass circulation periodicals.
