A substantial part of the work conducted by librarians today involves keeping up to date with current trends. This is particularly important in collection management and literature procurement. Though young adults in Sweden have previously been found to read less with worsening reading comprehension, a recent study suggests that their reading habits are changing. Young adults now read more, and it is increasingly popular to read literature in English. The aim of this master’s thesis is to study how a changed reading behaviour in Swedish young adults could influence the work of youth librarians’ collection management and literature procurement. Empirical data was produced through a survey that was sent to all public libraries in Sweden. The data was analysed by employing Bates’ (2002) model of different information seeking modes as well as McKenzie’s (2003) information practice by proxy. The concept of Wyatt’s (2014) model of selection cycle was used to analyse and discuss the findings. The result of the study shows that most youth librarians use information seeking monthly to keep up to date with literature. The librarians are likely to use information seeking to keep up to date with literature more often if they have noticed this recent change in young adults’ reading behaviour. Above all, how librarians use social media and interact with the public is significantly impacted by whether or not librarians have perceived a change in the reading trends.
