Series Notes:
1. This series was noted in a periodical called The Critic- June 1897.
The article stated that Trif and Trixy would be the first volume in a
series of books by American authors. These books were to be sold at 30
cents. Although Trif and Trixy was released in 1897, it was not within
this series. Rather it was by itself as a non series book and priced at
35 cents.
