This document provides a brief overview of a PowerPoint presentation (with accompanying slides) where the development of a detailed, online subject-specific glossary is discussed. The pedagogical justification for the creation and use of a glossary is presented. It is asserted that a subject-specific glossary has many advantages and useful features, and that it will help students to access the meaning and pronunciation of unfamiliar technical terms instantly and thus reducing much of the time and effort otherwise spent in lexical research, and that this is especially beneficial for nonnative speakers of English taking English medium courses. The paper is divided into several sections with the following subheadings: "the concept"; "the development of the online glossary"; "subject specific glossary versus other electronic dictionaries"; "the technology"; "the methodology"; "lexicography."
