The archives of J. Stuyt had been described on a number of lists. In processing the archive, the structure of the old list was largely maintained, the other old lists were incorporated into it. The archive was partly unpackaged and partly packed in portfolios that were too small, which damaged a number of drawings. A number of drawings will be restored.
The archive is arranged by place name in alphabetical order. A number of folders contained loose drawings, sketches and watercolors that were barely described. These have been appended to the corresponding records. Projects made by J. Stuyt and J.Th.J. Cuypers have been described separately. See the section 'Drawings archive of J. Stuyt and J.Th.J. Cuypers'.
Altarpieces, church furniture and other furnishings have been given their own access number, see inventory numbers 352-358. Books and documentation are housed in the library of The New Institute. They are marked 'PULCHRITUDINUS STUDIVAI HABENTES'. The documentation present in the archive (inventory numbers 362-366) is described in Appendices 3 and 4.
Some of the postcards have been kept separate and arranged by toponym in the postcard collection (archival code PBKV). The Stuyt archive contains postcards arranged by sender (see inventory number 3) and Appendix 1. The postcards collected in folders contain images of projects by Jan Stuyt or by Jan Stuyt and Jos Cuypers (see inventory number 362 and appendix 3). The postcards in the Cuypers family archives show much of J. Stuyt's work (see Cuypers and Co. archives).
A number of projects are on microfilm, see inv. no. s2 (keys 183-195, tape 1, 196-206, 231-233, tape 2). Glass negatives are packed in 2 boxes (inv. nos. s1 and s2), the description can be found in Appendix 6.
Glass negatives of the works of J. Stuyt and J. Cuypers can be found at Cuypers and Co.
Giacomo Stuyt, son of Jan Stuyt collaborated on or completed a number of projects. In a number of cases he took care of extensions of his father's works. This is mentioned in the description of the projects. If it concerns archive documents that are not included, the description can be found in the section 'Archive Giacomo Stuyt'.
