Makerspaces have spread to libraries in recent years, to promote
equitable access to technologies, expand services, and encourage
participation and learning. In this paper, scaffolding of learning is
studied from the perspective of library makerspace practitioners.
On the basis of interviews in six Danish libraries, we analyze
formal, non-formal, and informal activities and identify seven ways
of scaffolding. Three challenges are discussed: (a) fostering
community while ensuring inclusion in informal activities, (b)
avoiding to stifle creativity in short-term activities, and (c) finding
the role of the library in formal activities. We propose actions to
overcome these challenges, such as encouraging scaffolds across
formal, non-formal and informal learning activities and addressing
the educational role of the library.
