Almost any library around the world contains at least some guitar music, but this list was compiled to bring together all the information I could find regarding libraries which house large amounts music which is no longer in print. Of particular interest are the major guitar-only collections. The Rischel & Birket-Smith collection going online was a major influence on me to get this list started.
It has always been difficult to find music in libraries which have old collections because most information is still kept only in card catalogs. The internet has changed library access dramatically, but most libraries still have not put their card catalogs into searchable databases. This list will have all the information I can find regarding access to the the collections.
Any additional information you may have regarding these libraries, or libraries not in the list, is welcome.
