Tess Wilson writes: “After taking its conference virtual in 2020, YALSA turned to a hybrid symposium this year, featuring practical approaches, expert findings, and extensive resources for youth-serving library staffers. The 2021 YALSA Symposium (November 5–7) offered both online learning opportunities and an in-person experience in Reno, Nevada, with sessions covering such topics as teen mental health and teen-led podcasts. Focused on the theme ‘Biggest Little Safe Spaces,’ this year’s sessions were full of insight and innovation.”
