- When two separate pictures are included on a single reel, and only one is registered, the title of the other is given, if known, after the phrase, "On same reel with."
- Credits. The name of each person associated with the production of the picture is given, preceded in each case by a term indicating the nature of his contribution; i. e., producer, supervisor, director, writer, music composer, etc. For some of the earlier pictures the nature of the contribution is not available for all persons. In such cases the names of these persons appear first in the list of credits.
- Claimant and author of motion picture. Following the copyright symbol © the name of the copyright claimant is given as it appears in the application for registration. Address (city or country) follows the name if the claimant is also a foreign producing company. The name of the author of the photoplay as given in the application follows next when it differs from that of the claimant. The presence of two asterisks before the copyright symbol indicates that the name of the author was not stated in the application.
- Copyright date. For published motion pictures the date of publication is given. For unpublished motion pictures the date, or dates, of receipt in the Copyright Office of the title, description, and prints taken from the motion picture are given.
- The Copyright registration number is preceded by 1) the class letter L (motion-picture photoplays) or M (motion pictures other than photoplays), and 2) the letter P or U designating, respectively, published and unpublished works.
In the case of serial entries information relating to the entire serial precedes that relating to individual numbers or episodes of the serial. When the name, or the form of the name, of the copyright claimant of a serial changes, each name precedes its respective entries. The copyright symbol © always appears immediately before both the name of the copyright claimant and the copyright date. When duplicate numbers appear in a sequence of issues, arrangement of the duplicates is by copyright date. Omission of an item in a sequence does not necessarily mean that the item has not been registered for copyright; it may be included in the catalog under its specific title if the source information did not give the serial title.
Index
The second section of this catalog is a list of the names of the persons and organizations associated with the production of the motion pictures listed in the first section, and of the authors of the novels, dramas, or other works upon which these motion pictures have been based. The names of the persons listed in the statements of credits in the main entries are not included. The name of each person or organization is used as a heading, the form of which is either that appearing in the Official Catalog of the Library of Congress, or that most frequently found in the records of the Copyright Office. Similar names have been listed separately unless it is clear that they identify the same person or organization. Cross-references from different forms of the same name and from pseudonyms are included in the list.
Brief forms of names, particularly in the case of trade names, appear in the list when it has not been possible to identify exactly the full form of the name.
Under each heading are listed alphabetically the titles of the motion pictures associated with it, together with their respective year dates, or, for serials, the word serial, enclosed in parentheses, in lieu of a date. An asterisk preceding the title indicates that the name appearing in the heading is that of the copyright claimant.
Series List
The third section of this catalog lists the series titles which are contained in the main entries. The titles of the series are frequently given in varying forms. For each series, therefore, an established form, based on that most frequently used, is given as the heading. Following the heading are references to other series titles which appear to be related because the names are similar and the claimants are the same.
