“ The title card becomes in most cases a series card, since the title of an often-represented subject attracts to itself many names of artists. In such cases arrange the authors' names alphabetically, in columns, and against them write the names of the galleries where the works are to be found. Give class and author number in blue ink at the left.
C Gallery card. This card is a series card, and should show, a, name of gallery; b, names of the artists and their works in the gallery.
Ca Give official name of gallery preceded by the name of the city where it is located, with country in parentheses. ”

“ B Author. For photographs of paintings give one important name.
For photographs of sculpture give sculptor's name, where known.
For photographs of architecture give name of city followed by country in parentheses. London (Eng.)
C Title. For photographs of painting and sculpture use short, catch title, bringing, where possible, the important name first.
For photographs of architecture, make first word a word descriptive of the kind of building: Temple of Mars; Cathedral of Notre Dame; Basilica of S. Paolo.
D Gallery. This column is used for sculpture and painting only. ”

“ Those for the large size should have no front, but the case containing them should have doors.
Note.—Be very careful in handling photographs never to rub or pull one over another; always turn them from side to side, like the leaves of a book. ”
