History of the collection: The collection was compiled by two collectors, Dr Jan Jacob van der Harst (1881-1917) and GJPJ Bolland. After the death of Van der Harst, his collection was bought by the Hague chapter of the Society for Pure Reason and then donated to the KB via Bolland. In 1919, Bolland himself supplemented the collection with a donation of books and offprints from his own library.
Size: The Van der Harst collection comprises approximately 775 titles including periodicals, books and multi-volume works. The collection also contains a collection of reprints and newspaper articles, lecture notes, letters and two manuscripts. Bolland's collection comprises approximately 480 titles.
Accessibility: The books are listed in the KB online public catalogue.

Jan Jacob van der Harst was a physician and psychiatrist at Oud-Rosenburg in Loosduinen from 1906 until his early death in October 1917. During his study of medicine he became a pupil of Bolland, who introduced him to the work of the German philosopher Hegel. While working in Loosduinen he built up a collection of books having to do with Hegel and Hegelianism, which included the Dutch neo-Hegelianism inspired by Bolland. In 1912 the 'Society of Pure Reason' was founded, a national association of enthusiastic followers of the philosophy of Hegel, with chapters throughout the country. Van der Harst was a member of the society and attended Bolland's evening lectures given to the Hague chapter. After Van der Harst died, the chapter decided to purchase his Hegel collection and to donate it, via Bolland, to the KB. The KB annual report of 1918 mentions a catalogue of the Van der Harst collection. A hundred reprints of this catalogue were produced for the members of the Hague Bolland Society. In 1919, Bolland supplemented the collection with about 480 titles from his own library. Eighty of these contain annotations by Bolland himself. Approximately 70 titles are exclusively concerned with the philosophy of Hegel, while the rest are of a more general philosophic nature.
In 1925, Bolland's son donated the other, larger, portion of Bolland's library to the Leiden University Library, where the Bolland archive is also housed. In 1932, ten years after Bolland's death, a second organization was set up in addition to the Bolland Society. The aim of this organization, which was called the Bolland Foundation, was to set up a Bolland library and to promote the reissue of his works. In the period 1932-1943, the members of this foundation put together a large collection of books, brochures, reprints and manuscripts by and about Bolland, Hegel and Hegelianism. This collection (13 boxes in the archive; approximately 1,200 titles in the library) has been on permanent loan to the Amsterdam University Library since 1943.
Besides the Bolland archive in the Leiden University Library, the collection of the Bolland Foundation in the Amsterdam University Library and the books with Bolland's annotations in the sizeable remaining portion of Bolland's library in Leiden, the KB's Hegel-Bolland collection is important for the study of philosophy by and about Hegel and of neo-Hegelianism in the Netherlands. Of particular importance are the approximately 80 books with Bolland's own annotations given by Bolland himself and the German, Italian, Polish and Swedish 19th-century Hegeliana purchased by Van der Harst through the antiquarian market, which include several extremely rare editions: Antibarbarus logicus by Friedrich H.Th. Allihn, Halle, 1850; Die speculative Idee in Humboldts Kosmos by Gustav Biedermann, Prag, 1849; Una fissazione Hegheliana by Lorenzo M. Billia, Torino, 1898; Die Frage über die Entstehung der Arten by Franz Chlebik, Berlin, 1873; Gott und Palingenesie by August Cieszkowski, Berlin, 1911 (2nd impr.); Selbstbewußtsein und Offenbarung by Kasimir Conradi, Mainz, 1831; La natura e l'incivilimento by Niccola Marselli, Torino, 1879; De Hegelii notionibus finiti infinitique commentatio by Th. Weber, Vratislaviae, 1868; Cieszkowski's Philosophie der Tat by Adam Zoltowski, Posen, 1904. Also deserving of mention are the lecture notes taken by Van der Harst at lectures and cycles of talks given by Bolland, as well as notes he took on reading certain books and journal articles, a few letters (and drafts of letters) by him and to him, and a collection of articles by the philosopher and teacher Klaas Johan Pen (1875-1932). Also included is Bolland's 1903 manuscript Zuivere rede in hare toepasselijkheid op leven, ziel en geest and the manuscript, galley proofs and doctoral thesis Over het onderscheid tusschen de wetenschap van Hegel en the wijsheid van Bolland, by Pen, dated 1915.
