In the second volume of Rullmann’s bibliography, there are numerous and frequently extensive citations from Kuyper’s writings—even considerably more than in the first volume (see 1923.07). Rullmann also includes complete pieces.

Seven prefaces are reprinted: 1881.01 (pp. 45–46); 1888.04 (p. 219); 1888.06 (pp. 220–221); 1889.15 (pp. 273–274); 1890.06 (pp. 284–285); 1890.08 (pp. 297–298); and 1890.11. (pp. 315–322). Five articles are reprinted from De Heraut: a piece from no. 265, January 21, 1883 about Article 36 of the Belgic Confession (pp. 90–91); “The New Edition of the Old Bible” (cf. 1895.11) from no. 924, September 8, 1895 (pp. 302–307); “Fraternal System. XVII” from no. 632, February 2, 1890 (pp. 328–332); “Fraternal System. XX. (Conclusion)” from no. 641, April 6, 1890 (pp. 332–335); and an article from no. 671, November 2, 1890 in which Kuyper introduces 1890.13 (pp. 335–338).

Three asterisms are also reprinted from De Standaard: “De Beaufort’s Apologia” (cf. 1889.13) from 18 (1889), no. 5361, September 2, 1889 (p. 255); “Dr. Kuyper 1875 and 1890,” about perceived inconsistencies in Kuyper’s political ideas from 19 (1890), no. 5529, March 20, 1890 (pp. 281–282); and “1875–1890,” about the same question, from 19 (1890), no. 5532, March 24, 1890 (p. 282).

The bibliography includes three short comments: a piece reprinted six times in De Heraut, no. 44, October 13, 1878–no. 49, November 17, 1878 about the question whether the fact that future pastors were being equipped for their duty by “modern” professors of dogmatics at the Dutch Universities could continue to be passively tolerated (p. 1); a comment from De Heraut, no. 477, February 13, 1887 about the publication of the Amsterdamsche Kerkbode (pp. 200–201); and a short comment (pp. 342–343) related to 1890.13 and reprinted from the press review in De Heraut, no. 684, February 1, 1891.

Other items reprinted in the bibliography include: an article from Amsterdamsche Kerkbode 1 (1887), no. 8, March 27, 1887 (pp. 203–204; see 1887.18); an advertisement (cf. 1882.01) reprinted from De Heraut, no. 193, September 4, 1881, which was also published in no. 194, September 11, 1881(p. 68); a letter (see 1882.11) reprinted from De Heraut, no. 258, December 3, 1882 (pp. 59–61); another letter (see 1895.21) reprinted from De Bazuin 43 (1895), no. 46, November 15, 1895 (pp. 179–180); a telegram (p. 186; see 1887.02); the whole of the poem “Aan Beets” (pp. 62–63; see 1882.04); and an undated sketch, “Method of Study” (pp. 263–272), which was written for theology students at the Vrije Universiteit to instruct them about the demands of theological study on faith, disposition, and time, and to provide advice about fields of study, books, and study strategy.

The second volume of Rullmann’s bibliography (covering 1879–1890; no. 61–120) had previously been published in forty-four installments in De Reformatie (1923–1925) and continued in thirty-four installments in Gereformeerd Jongelingsblad (1926–1928). RKB 88 seems to have fallen into the year-and-a-half gap between the publication of the series in De Reformatie and in Gereformeerde Jongelingsblad because it did not appear as an installment in either publication.
