This document discusses creating narrow listening libraries to help students improve their listening comprehension skills. It describes how a narrow listening library contains several short listenings on focused topics by different speakers. Students can choose which topics and how many times to listen. The rationale is that narrow listening provides comprehensible input, improves motivation over typical listening exercises, and is practical to implement. The document outlines the development of a narrow listening library at Poole Gakuin University, including recording and editing listenings using Audacity and hosting them on a Moodle site.
