Designed and maintained by Robert Glaubitz for both singers and fans, this site indexes information on over 1,200 arias from 170 operas, offering some 380 translations, 1,000 aria texts, and 223 MIDI files. Visitors can undertake a quick keyword search from the splash page or proceed to the main page for advanced searches and browsing by alphabetical entry or resource type (translations, MIDI file, operas, etc.). The entries are cross-referenced, and most include links or information on finding recordings and related materials. Also included on the main page are a what's new listing and a respectable collection of briefly annotated links.
