2. _Production statement._ The name of the producing company, i.e., the company responsible for the existence of the picture, follows the title. In some instances two companies or organizations are concerned with the production of a film, one with the physical production, i.e., photographing, editing, sound recording, etc., the other with planning, distributing, and sponsoring the motion picture. In such case the company concerned with physical production is named first, followed by the preposition _for_ and the name of the other company. The name of a foreign producing company is followed by the name of the city or country in which it is located. When the name of a person or organization is given in the records of the Copyright Office preceded by the phrase _presented by_, the name, together with the phrase, follows the date (see item 3 below). 3. _Date._ For published works, the year date of copyright (see item 10 below) preceded by a lower case c, (e.g., c1941) follows the production statement. If a production date different from the copyright year date is given in the records, this information follows the copyright date. For unpublished works, no date is given in this position in the entry. 4. _Physical description._ A full physical description contains information relating to 1) the length of the film, given in running time, footage, number of reels or frames; 2) color or black and white versions; 3) sound or silent versions; 4) width of the film. Few of the entries in this catalog for the period prior to 1946 contain full physical descriptions because information on these points was not included in the records of the Copyright Office. 5. _Notes._ Certain information which helps to identify the motion picture more exactly is given in the form of notes: a. The title of the series to which a motion picture belongs is given immediately following the physical description. b. Phrases further identifying persons or organizations connected with the production of a motion picture, such as _Warner Bros.-First National picture_, _Frank Capra production_, etc., are given in a note following the series note. c. Information relating to other titles by which the motion picture is known, to other versions, to related material to be used in connection with the showing of the motion picture, or to the source material on which the motion picture is based, is given in the order named. 6. _Summary._ A brief statement describing or characterizing the motion picture is included whenever it has been printed previously in an issue of the _Catalog of Copyright Entries_.
