As in the first volume, entries are divided into individual language sections for ease of reference. Each section begins with general information about the cooperating language specialists, the area where the language was spoken in 1910, and explanation of library and depository symbols, and a section bibliography. Introductory essays survey the development of the labor and radical press as it relates to the particular ethnic group in question. The annotated bibliography contains all periodicals that appeared more than once a year, along with brief descriptions where available. Finally, each section contains complete title, geographical, and chronological indexes to the periodicals included.
