The Journal of Economic Literature (JEL), first published in 1969, is designed to help economists keep abreast of the vast flow of literature. JEL issues contain commissioned, peer-reviewed survey and review articles, book reviews, an annotated bibliography of new books classified by subject matter, and an annual index of dissertations in North American universities. You can browse the JEL by issue or search all issues through the Electronic journals UU (see tab 4).
To many economic publications the subject codes of the Journal of Economic Literature (JEL) Classification System have been added. The "JEL" classification system is a standard method of classifying scholarly literature in the field of economics. Use the guide to gain insight on how JEL Codes are used to classify articles, dissertations, books, book reviews, and working papers.
