Textbooks are defined as materials that are designed specifically to be used in a classroom setting which covers a specific topic. The TDRL textbook collection is a representation of titles being used in the Clark County School District (CCSD). Titles implemented outside of the CCSD curriculum are included by faculty request. Textbooks from all grade levels and subject areas within the CCSD are collected.
Higher Education level textbooks are not collected unless they qualify as professional materials (see Professional Development Collection)
