Chapters
SLA is organized into 55 regional Chapters that elect officers, issue bulletins or meeting announcements, hold three to nine program meetings during a year, and initiate special projects. Members in all classes may affiliate with the Chapter nearest their own preferred mailing address (either business or residence) without charge. They may also affiliate with more than one chapter for an additional fee.
