My reading of LC's Catalog of Copyright Entries, Motion Pictures, 1912-1939 suggests that the Disney cartoons were released as discrete items and not as a series. The index indicates that Looney Tunes was a series. I note as well that cartoons were registered in the names of Disney (Walt) Enterprises, Disney (Walt) Productions, Disney (Walt) Productions, Inc., Disney (Walt) Productions Ltd., and Disney, Walter E. ---Yet more reasons to appreciate careful bibliographers. -Henry Breitrose Dept. of Communication Stanford
