Also included in this series are newspapers from the west coast. The titles Placer Times and Transcript, Steamer Union, and The San Francisco Herald are all extremely fragile. There are also two posters of San Francisco.

Series V. Printing Materials contains printers' cuts and a seal. Also included in this series are two stereotype flongs, pasted paper forms into which an image has been pressed. These flongs, or matrixes, were pliant enough to register an impression and sufficiently heat-resistant to tolerate the molten-type metal poured into the flong to create a stereotype plate of the image.
