The database JSTOR (short for Journal Storage) covers many different scholarly disciplines. JSTOR is unique in that it is comprised of archived collections which means they encompass the complete run of each journal starting with its first issue up until a certain date, usually excluding the most recent years of these journals. In short, it's good for a contemporary/historical view of a topic, but not the most recent view.
