News from the Library of Congress.In November 2008, the Library of Congress Acquisitions and Bibliographic Access Directorate approved a Timeline and Plan for the Next Five Library of Congress Genre/Form Projects. In accordance with that timeline, the Policy and Standards Division (PSD) is beginning to develop a genre/form thesaurus for music. LC’s Music Division and other interested groups are collaborating with PSD in this effort.[From Genre/Form Thesaurus for Music]Information about the project, including tentative lists of genre/form terms and terms denoting medium of performance, may be linked to from PSD’s genre/form web page.
How fascinating, but how complex to try to order the fluctuations of musical fashion. I hope they will find room from thrash-skiffle, the form pioneered by Brighton's Curst Sons
