This display was a new initiative at UNT Libraries that is similar to the Monthly Books Display but has a chosen theme that runs for a full semester. The theme of Spring 2018 was "Adulting", a popular Millennial word used to describe activities that are seen as very Adult, such as doing taxes, paying off student loans, etc. "Being an adult" is often met with trepidation, so the figure at the bottom is distressed by the Adult world ahead of him. The thought bubble filled with very Adult things looms over him in an oppressive way that takes up most of the visual space of the design.
The general idea is "adulting is scary but these books can help you," and the display was very popular amongst the students.
