This study examined whether three renovated academic library spaces encouraged group work as intended. Hourly observations and a questionnaire documented group work use, space preferences, and suggested improvements. Compared to the three renovated spaces, significantly more group work occurred in an unrenovated space that was more open, spacious, and visible. Questionnaire results indicated that noise levels, available space and furniture, lighting quality, location, and operating hours also influenced group work space preferences. Suggested improvements included designated quiet and talkative areas, reservable space, and additional tables. Findings offer insights to inform future library group work space research, design, and evaluation.
