Query: transformation of cinema! Great read!

the University of California seriers on American Cinema is truely a wonderful collection on the movies. "Transformation..." gives a pretty detailed account of the changes in exhibition and production as well as the presentation of films to the public during the nickelodean phase. It debunks some myths concerning this period concerning Hollywood versus New York and New Jersey, the invention of the star system, the role of the director in production, etc. It also give a lot of detail on the changes in distribution during this period. A bargain for any film buff.
