The Rev. J.C. Rullmann (1876–1936) modeled his Kuyper bibliography on a remarkably expansive definition. Two motives appear to have been decisive. First, he strove to keep Kuyper’s ideas alive among the older generation and to unlock his legacy for a new generation. He therefore had the tendency to let Kuyper speak more and more through the bibliography. The second motive was his conviction that Kuyper’s writings should be understood and described in their historical context. He thus included many references to secondary literature, frequently with citations. By tracing lines of thought and relations in Kuyper’s work, Rullmann produced an interesting, instructive, and compelling work. But he clearly considered the bibliographic information and the publication chronology of lesser importance and scarcely a subject for research and description. Translations are only mentioned in passing—if they come up for consideration at all. Closely following the chronology of Kuyper’s publications in the 1915 catalog by J.H. Kok, Rullmann’s bibliography would end up listing 223 entries in all (excluding the additional titles in vol. III, pp. [469]–470).

An index of keywords is included in each of the three volumes of the bibliography.

Rullmann assembled a considerable collection of Kuyperiana and several of Kuyper’s texts that can no longer be discovered in their original edition were preserved probably thanks to his collection and in any event thanks to the design of his bibliography.

The frontispiece is a slightly reworked fascimile of a lithographed drawing designed in 1892 by Jan Veth (1864–1925) and presenting Kuyper writing at his desk. See also the frontispiece of this new bibliography.

The contents of this first volume had previously been published in installments in De Reformatie 2 (1921/1922), no. 1, October 7, 1921–3 (1922/1923), no. 25, March 23, 1923.
