"The HJG aims to be a starting point for researchers, graduates, students, librarians and other interested persons and intends to provide an easy access to up-to-date information. It is updated regularly -- all two weeks at the moment. The Periodicals Directory provides information about abbreviations, content, editors, publishers, publication dates, frequency, languages, ISSN and websites. The Discussion Lists Directory informs about content, subcription, editors, publication dates, languages and websites. At the moment not all periodicals and discussion lists are described completely. Both directories can be browsed by title, period, region and subject, the periodicals directory also by language and e-journals and e-newsletters. The Online Articles Index provides links to articles published in electronic journals, and the Online Reviews Index lists reviews published by electronic journals and mailing lists."
