This study used a quantitative survey to determine whether upper secondary students were motivated to read by their school libraries’ reading promotion activities, as well as how these activities affected the students’ reading habits. The study also investigated the students that had not attended these activities, in order to discover correlations that might affect whether a student attends one of these activities or not. The online survey was distributed to 8 schools, and 221 students answered the survey. The data was later analyzed using Spearman’s rank correlation coefficient together with descriptive statistics. The study found that many students felt motivated to read after they had attended reading promotion activities, and a few students started reading more after they had attended an activity. Visits to schools from authors turned out to have the most positive effects on the students’ reading motivation and reading habits. Many students did not believe the library could arrange an activity that would interest them, and the study found no clear correlations as to why that was other than the fact that they seemed to lack interest in these activities. The results also show that a lot of students would be interested in attending activities at their school libraries if their school libraries arranged more activities that could improve the students’ study techniques.
