This paper aims to show the presence of thematic ordering in Spanish teaching materials in the United States, the construction of a textual series and its evolution over time, and the contribution of teachers, lexicographers, and grammarians to the history of linguistics. The vocabularies ordered by designative domains composed by Nicolas Gouin Dufief, by Edward Barry, by F. F. Moritz Foerster, by the author of ¿Habla Vm. Español?, by Luis Felipe Mantilla, by Antonio Ramos Díaz de Villegas and by Alfred Ronald Conkling constitute an interesting contribution to the history of Spanish in the US that has yet to be made.
