The National Music Museum has a documentation centre that specialises in organology, history and theory of music, where reference works for the study of music can be found.
The documentation centre is open to the public for consultation and has information about musical instruments from many parts of the world (their construction, history, representation in works of art - musical iconography), musicians and history of music, among others. Its main focus is on classical music, however, it also has documents related to popular music, fado, contemporary music and jazz.
Roughly 3000 works are available for consultation: theses, facsimiles of treaties and methods for instruments, instrument museums' catalogues and exhibitions; runs of such important periodicals such as Arte Musical, Early music, Le Monde de la Musique, Ritmo and World of Music and also some studies on instruments from the Museum's collections and instrument makers.
The documentation centre's publications are recorded informatically and can be searched online on the Cultural Heritage Libraries website (choose Biblioteca do Museu Nacional da Música).
