We live longer and healthier lives and have fewer children, which means that the demographics are changing significantly with a larger proportion of healthy older adults. This study aims to explore what the discourse around older adults looks like in the Swedish public library plans and what consequences it may have for the target group and activities aimed at it. To answer the research questions a discourse analysis of age-related signs and in what context they occur in the library plans was done. The conclusion is that older adults are most often represented in the word all and in different contexts of disabilities. The discourse of the library plans seems to mainly identify older adults as belonging to what in gerontology is described as the fourth age, while the third age appears to be outside the current discourse. A shift in language in the library plans towards a more positive image of older adults that also recognises healthy older adults could mean that the library achieves better conditions to attract the large and ever-growing target group of older adults.
