NPI Archives

NPI Archives

The NPI archives gather the work of the founders and consultants of the former Nederlands Pedagogisch Instituut (NPI – Institute for organisational development), founded in 1954 by Bernard Lievegoed. In the spirit of the collective thinking of those founders, everything here is freely available to everyone.

What you will find are the models, theories and essays that lie at the root of much of today's thinking in organisational development – many of them tracing back to Lievegoed's own writing and teaching at the NPI, and to the anthroposophical idea of the threefold social order that underpinned much of the NPI's approach. See the about page for more on this background.

After the NPI ended its activities, the Cloverleaf Foundation kept the archives alive and accessible, and has now handed their hosting over to the Association for Social Development (ASD). On behalf of the ASD community, we warmly thank the board of the Cloverleaf Foundation for entrusting us with this collection, which we will preserve and cherish.

324 documents are catalogued here, searchable in full text and free to read and download. Almost all of them are in Dutch or German; for a quick translation, DeepL and Google Translate both work well.
