The Glanville Books Glossary App is a handy reference tool and learning aid for anyone studying economics for the International Baccalaureate Diploma. Key economic terms from the current IB syllabus are clearly defined, with click-able links provided to related concepts from within the definition. If a concept is relevant only to Higher Level students, this is clearly indicated. Details of additional resources for students and teachers of IB Diploma economics, including the original textbook (now in its third edition), two workbooks, and an eBook, can be found at www.glanvillebooks.co.uk.
