The Cerritos Library now offers the Mango Languages online language-learning system. Mango is free for all library patrons. Each lesson combines real-life situations and audio from native speakers with simple, clear instructions. The courses are presented with an appreciation for cultural nuance and real-world application by focusing on the four key elements of language learning: vocabulary, pronunciation, grammar and culture. Mango offers access to 60 foreign languages and 17 English courses.
