The Luthier's Library has more than 100 instruments currently in the site with additional instruments being added regularly. For each instrument there are more than 250 measurments and a minimum of 15 photos. Interior pictures are included whenever possible. The selection runs the gamut from 17th Century Italian makers to 20th Century makers from a number of countries, including Egypt. Our mission is to expand the database to have a number of instruments from the same maker and to continue to update the software to create a searchable fingerprint for each maker.
