These scores are smaller than normal scores, and are kept at the end of the main score section. You would use them to study the music - they are generally too small to play from. You will find that a lot of orchestral works come in the form of miniature scores. Another call number which you will occasionally come across is Whittaker Music , e.g. Whittaker Music TB740.101 4-OX . There are also a small number of Whittaker miniature scores - these are shelved together in the miniature score section.
Folios always have a small f at the start of their call number.
They are kept on a separate shelving unit - see the map of the Music section to locate this. Once you have found the score that you want, write down the Call Number , e.g. Music SS300.520 667-BRE . Use the range guides at the end of each shelf and the map of the Music section to locate the right area. Sometimes you will need to look carefully at the Catalogue entry for a score to check practical details. For example, you might want to know if a score also has parts which you can play from.
