Strongest direct peer given overlapping urban Dutch library market and similar municipal funding model.
- Bibliotheek Utrecht: Utrecht public library operating as a foundation with multiple branches, extensive community programming, and digital lending. Comparable in progressive programming (Taalhuis, Vindplaats-equivalent school services) and urban demographic focus.
- Bibliotheek Eindhoven: Public library in Eindhoven with similar smart-city integration, digital learning programs, and Taalhuis-equivalent language services. Comparable foundation structure with comparable membership tiers and progressive programming philosophy.

Emerging players

Broad incumbents

Directly comparable to DOK as a municipal public library foundation with progressive programming, though at significantly larger scale.

Acts as infrastructure provider and policy maker for the Dutch public library sector; comparable as ecosystem partner rather than direct competitor.
