BigSig – Technology interest group for all levels of tech-savvy

SLING – Network of school library staff throughout LCLS, to provide quality library services for students and teachers and to promote the importance of school libraries in increasing student achievement.

SWAYS – Network of youth services staff throughout LCLS, to advocate quality library services for youth and to promote the importance of those services
