The complete Music Online suite cross-searches more than 88,000 tracks, 285 hours of video, 13,632 scores, and over 45,000 pages of text reference, from over 150 different record and video labels, print publishers and score publishers, such as EMI, Boosey & Hawkes, Opus Arte, Hyperion, Six Degrees Records, Smithsonian Folkways, Edition Peters, Merce Cunningham Dance Foundation, INEDIT, and others.
You can create centralized playlists with one single login, bringing in materials from Alexander Street databases or material anywhere on the Web.  The robust indexing allows users to browse and search by genre, historical event, album, track, score, people, classical work, cultural group, ensemble, instrument, label, place, recording date, reference work, role, subject, time period, venue, and video.
For example, you can browse by instrument “banjo” and immediately access a bluegrass recording by Ralph Stanley, a folk recording by Pete Seeger, multiple images of banjos, articles on the banjo from various reference sources, and a twentieth-century score by David Del Tredici featuring the banjo.
If you are looking for scores, recordings, and videos of particular classical works, you can use the Classical Works browse, which will provide all relevant results for a particular composition.
