The Local Information Working Group (LIWG) of Thailand’s provincial university libraries holds main responsibility for digitising Thai local information (LI), a resource that shares many characteristics with what in other contexts is described as Indigenous and local knowledge (ILK). This study therefore explores how the digitisation activities of the LIWG correlate with claims of culturally responsive and responsible ILK representation, and how this work can be understood through the perspective of Bhabha’s Third Space. The study is based on interviews with 23 LIWG members, collected in 2016–2017. A guided, qualitative content analysis focused on uncovering themes of digitisation tools and methods with Third Space relevance as supporting or hindering essentialism, fixity and hybridity in LI representations. The findings illustrate that whereas the digitisation itself, field studies, language choices and outreach activities offer certain Third Space potential, this is underdeveloped and largely circumstantial. Third Space potentials are further likely to be restricted or hindered by uneven distribution of internet access, digital literacy, standard Thai proficiency and university/academic library accessibility among the Thai public in general and LI holders in particular. Overall, marginalised groups are excluded, and LI holders are positioned as passive contributors and recipients of digitised LI, suggesting a reversed sort of ‘self-essentialism’ on behalf of the dominant culture. In conclusion, two aspects in particular require further attention for libraries engaging with digitisation of ILK types of resources: the inclusion of national, societal level participation into participatory approaches; and the incorporation of functionalities for user interaction, holistic knowledge representation, multiple languages and cultural protocols into ICT for representation and use. The study provides a unique application of Third Space as analytical perspective on library digitisation of LI/ILK types of resources. Methodologically, the study is case specific, limited to a cross-section in time, and to data from interview accounts of LIWG members.
