JSTOR contains an archive of over 600 academic journals in the arts and sciences right back to the beginning of each title. You cannot search for articles by subject but there are other excellent search mechanisms including author, title and full text article searches. JSTOR now also includes many ebooks from academic presses. Most ebooks are at lease three years old, although there are a few newer titles. All ebook offerings the Tyndale has access to will be discoverable in WorldCat as well.
