Book excerpt: The Language Center Handbook 2021 is the latest volume in the International Association for Language Learning Technology's (IALLT) Language Center Management and Language Center Design volumes. The chapters span a much broader geographical area than the previous Language Center Handbook (2018), including authors based in Canada, Germany, Hong Kong, Japan, Mexico, and the US. Unlike previous IALLT volumes, the definition of language spaces is expanded to embrace language labs, language centers, and self-access learning centers. The topics cover the origins and fundamentals of language spaces, designing and redesigning these spaces, and technologies used and supported by language spaces. For the directors and staff of language spaces, this publication is a valuable resource for developing and reimagining affordances and services. For administrators, the Language Center Handbook 2021 provides a basis for understanding the potential and unique value of language spaces.
