Alzheimer's Disease (AD), the most common cause of dementia, is an incurable neurological disease with an unknown cause. Since AD is not only social and health challenge but also an economic and fiscal burden and its prevalence is expected to grow exponentially as world population gets older, in 2012 the World Health Organization (WHO) and Alzheimer's Disease International (ADI) recognized dementia as a global public health priority. Although librarians have not generally been recognized as professionals caring for persons with dementia, recent research indicates that public libraries can contribute to the development of dementia friendly communities by supporting social inclusion, self-efficacy and capacity building of persons with AD, and by providing support to their informal caregivers (CGs). The research reported in this paper aims to examine the role of Croatian public libraries in building a dementia friendly communities, in a country where information, health and social care systems for D patients and their CGs are not sufficiently developed (Rusac, 2016; Petr Balog et al., 2020). With the help of quantitative (online survey) methodology authors explore how Croatian public libraries tailor their spaces, collections, programs and services in order to enhance the everyday experience of persons with AD and their CGs.
