De Navorscher [The researcher] was published “as a means for the exchange of thoughts and literary life between all who know anything, have anything to ask, or can solve anything.” It was modeled upon Notes and Queries, an English periodical published since 1849. De Navorscher printed Kuyper’s request for printed or unprinted Lasciana hidden away in private collections on behalf of his edition of A. Lasco’s Opera (see 1866.01). Responses were to be communicated via De Navorscher. The only reply he received did not provide any useful information.
The appeal was reprinted many years later in De Standaard, no. 11399, May 17, 1909, along with a remark that it was probably Kuyper’s first publication for the press. For a similar request, see 1863.03. Kuyper also put forward a request for information in an 1881 advertisement in De Heraut (see 1882.01).
