Page  495 ï~~Recent Changes in Computer and Electronic Music Subject Headings at the Library of Congress by Deta S. Davis Library of Congress ABSTRACT The Library of Congress is radically revising its approach to the subject access of computer and electronic music. This paper will briefly cover the past practice of subject access to this medium and will outline the new developments. Since most academic libraries in the United States, and many libraries elsewhere, use Library of Congress Subject Headings, this paper will be useful to anyone who wants to find computer and/or electronic music in a library. Because there was no adequate means of subject description, the Library of Congress has heretofore treated musical works with electronic and computer elements differently than any other type of music. Electronic and computer subjects were separated from all other performing forces, even though many musical works involve mixed media. One heading was assigned for the instrumental and/or vocal mediums as if there was no electronic/computer participation in a work, and a second heading for the electronic or computer medium. For example, a work for violin and computer would have two subject headings Violin music and Computer music. A work for two violins, viola, and violoncello with electronic tape received the subject headings String quartets and Electronic music. A work for orchestra and live electronics received the headings Orchestral music and Electronic music. The Library did not have the subject heading structure available to combine these headings into one. The Library did have a few subject headings that recognized electronic and computer music as a full part of the performing forces, such as Vocal duets with electronic music, Choruses, Sacred (Mixed voices) with electronic music, and Songs (High voice) with computer music. In all these instances the electronic and computer element is the sole accompaniment to vocal forces. If any other instrument was added to the work, the two-heading approach was utilized. This system was not satisfactory to anyone, and owing to the growth in the fields of computer and electronic music we had to find a new way to provide subject descriptions before the original system completely collapsed. Searching for works with electronic and computer forces has been discouraging at best. Since this genre is found predominantly on sound recordings rather than scores, the chance of false hits increases with multiple works. ICMC 495

Page  496 ï~~In 1987 I submitted a proposal to the Office of Subject Cataloging Policy for a new approach to subject headings for electronic and computer music. The Policy Office suggested an overall policy change to our approach in the Music Section rather than piecemeal changes. In 1989 the Working Group on Electronic Music of the Bibliographic Control Committee of the Music Library Association formed to address this issue. The term "computer" clearly delineates works with computer elements. The challenge was to devise a means to describe works with electronic elements with Library of Congress Subject Heading language, and then fitting it into the existing heading structures. The two headings also needed to be developed in tandem. The term "electronics" seemed to fit all requirements. However, the term also has other meanings within the Library of Congress Subject Headings. After the head of the Subject Policy Office approved its usage in our context, I submitted a proposal that revamped the usage of the electronic and computer music subject headings and submitted it to the Working Group on Electronic Music at the 1991 Music Library Association meeting. The group amended the proposal and decided to issue a survey to librarians and composers of computer and electronic music to find out under what terminology people expected to find electronic and computer music. In particular, the survey sought to discover what was understood by the term "electroacoustic," which also had been considered for a subject heading. The response to this question was quite revealing. Not one answer for the definition matched any other. Definitions ranged from anything out of a loudspeaker, and amplified acoustic instruments, to music created by a computer. With such inconsistent interpretations of the term electroacoustic, we could not use the term. After the survey, I put together another proposal that incorporated the changes recommended by the Working Group on Electronic Music. I submitted this for discussion to the Music Section, Special Materials Cataloging Division at the Library of Congress. After much lively debate over two long meetings, a rather elegant solution emerged. In works where the electronic/computer part(s) are used with other instrumental and/or vocal mediums, there will continue to be a twoheading approach. The first heading is assigned for medium or form with qualifiers as appropriate, including qualifiers indicating the electronic or computer part as a full participant in an ensemble. Examples are: Quartets (Trombones (3), electronics); Flute and computer music; and Vocal trios with computer and instrumental ensemble. An additional heading is assigned which uses the term Electronic music or Computer music as genres, followed by qualifiers when there are other instrumental and/or vocal mediums, or multiple electronic/computer parts without other instruments. The headings are qualified by medium with the word electronics or computer used as the qualifier for the electronic or compute, part. Two examples are: Electronic music (Piano, ICMC 496

Page  497 ï~~electronics (2), violin) and Computer music (Voices (4), computer). The proposal has been forwarded to the Subject Policy Office and it is hoped that it will be approved without further amendment. An example of the effectiveness of the new approach can be obtained by considering the catalog records shown in Examples 1, 2, and 3. Since the first work is for computer alone, there is no change from the earlier practice. The second work is for flute, clarinet, violin, violoncello, electronic keyboard (Kurzweil Midiboard), electronic percussion (KAT), and live computer electronics. The subject access for this work under the new approach is: 1. Septets (Electronic keyboard (Synthesizer), clarinet, flute, percussion, computer, violin, violoncello); and 2. Computer music (Electronic keyboard (Synthesizer), clarinet, flute, percussion, computer, violin, violoncello). The order of the instruments is prescribed in the preface of the Library of Congress Subject Headings: keyboard instruments, wind instruments, plectral instruments, percussion and other (electronics and the computer are considered "other"), bowed strings, unspecified instruments, and continuo. The second and third examples are OCLC printouts from other libraries for the same sound recording following the old practice. Note the contrast between the septet heading (including the computer) and the additional computer music heading with qualifiers, and, the sextet heading in tandem with the unqualified computer music subject heading. The third work for four amplified voices and computer generated tape has the subject headings: Vocal quartets with computer music; and Computer music (Voices (4), computer). The OCLC libraries had considerable difficulty with this work with one using Vocal quartets with electronic music and the other, Vocal quartets, Unaccompanied. Each is misleading at best. The fourth and last work is for two guitars, percussion, and live computer electronics. The first subject heading is Quartets (Guitars (2), percussion, computer); and the second, Computer music (Guitars (2), percussion, computer). Formerly, as shown on the OCLC printouts, this received the subject heading: Trios (Guitars (2), percussion). I hope you can see an improvement. I have tightened the definitions for electronic and computer music to provide clearer guidelines to librarians so they have a better chance of using the correct terminology. The proposed scope note definitions for electronic and computer music are found in Examples 4 and 5. Other computer-music related headings we have recently established are: MIDI (Standard), Drum machine, Sequencer (Musical instrument), and Sequencer (Music software). How can this change help you? It should be significantly easier to find electronic or computer music in a library data base. The medium or form headings provide an access point that contains a richly descriptive phrase. The genre-type headings will generate a comprehensive and cohesive file under specific terms. ICMC 497

Page  498 ï~~How can you help us? We can only provide bibliographic access that is given to us. Include a specific listing of instruments and voices on your sound recordings. Describe in program notes whether the piece is electronic/analog or computer/digital. Additionally, we will give an access point to an established studio where a work is realized if it is mentioned on the sound recording or its program notes. Our goal is to make this music as accessible as possible via the catalog record to people who want to hear or study it.
