S-97 However, where registrations are being made in Classes Band E, it may be necessary in certain cases to send a warning letter. The law provides that the notice for a periodical shall appear "either upon the title page or upon the first page of text of each separate number, or under the title heading." Thus, if when the folded sheet is opened out, the notice does not appear on the side of the sheet containing the title, we should send a warning letter since we could not be sure that the other side would be regarded as "the first page of text of each separate number." In the case of a musical composition, the law provides that the notice shall appear "either upon its title page or the first page of music." If, when the folded sheet is opened out, the title page the first page of music appear together on the same side of the folded sheet and the notice appears on the  side, we should sent a warning letter.
