One of the great things about the Internet is the large number of lists and databases available online. The Sample Library Archive (www.samplelibrary.net) contains hundreds of files for use with a range of samplers. Would you like to trade a cool sound, drum loop, or Yamaha A3000 instrument? Upload it to the archive; then, browse for something you'd like in exchange. The MP3, A3K, WAV, and other files found in the archive are free and designed to be shared by the online electronic-music community. … The All Music Guide (www.allmusic.com) attempts to be a complete and comprehensive list of all music in all styles recorded during the past century. The styles include rock, blues, country, jazz, reggae, rap, and experimental. Each genre is broken down into subcategories and historical styles. A brief description of each category's characteristics is followed by a list of representative albums and artists, all heavily cross-referenced and hyperlinked. The Music Maps section helps users explore the evolution of different styles. The music of classical composers such as Beethoven and Bartok is covered on a companion site, www.allclassical.com. … Bug Music (www.bugmusic.com) is an independent music publisher with offices in Los Angeles, New York, Nashville, and London.
