As of March 7, 2022, the guidelines for face coverings have changed. Here's a little more information:
Do members of the general public have to wear a face covering in the Library?
Face coverings are no longer required indoors at the Library. We continue to recommend that face coverings be worn indoors, particularly for those who are not fully vaccinated.
Where can someone get vaccinated?
There are many sites offering vaccinations. We encourage everyone to get vaccinated as soon as possible. Site listings are updated regularly here: https://www.cityofpasadena.net/public-health/covid-19-vaccine/#vaccination-sites
