BookRecommendationChromeAddon is a Chrome extension designed to recommend related books from the University of Tsukuba Library Information Science Library to Wikipedia viewers. It aims to enhance students' learning experiences by suggesting relevant books while browsing Wikipedia within the university's library. The recommended books are displayed just before the second h2 tag, providing students with additional resources for further study.

However, there is a delay of approximately 55 seconds before the related books are shown. The extension's main JavaScript file directly lists three recommended books for each of the 1.07 million Wikipedia pages, resulting in this delay. The developer is open to suggestions on how to improve the speed of displaying recommended books and can be contacted at
