In 1837 Otis Broaders co-published with Jas. H. Weeks, a New York publisher, Rollo Learning to Read, the second book in the Rollo Series. It is uncertain whether it also published book #1 Rollo Learning to Talk at that time. Presumably it did. These two books have not been seen.

Otis, Broaders only published the four Rollo Philosophy books in 1843. The books are 6.5 x 4.5.
