Books are written or printed works produced by one or more authors. Individuals or committees with expertise in the field often edit books. Because they provide comprehensive information on their subject at the time of publication, books are very valuable in the research process. For many subject areas this is the best starting point for research. Many books contain valuable bibliographies at the end of each chapter or at the close of the book. This provides an excellent entry point into the subject material as well to the authors publishing in a particular field of study.
Unlike more general subjects such as History or Psychology, most Music books are contained within the same “class” in the Library of Congress classification system.
| M | Music. |
| ML | Literature on music. |
| MT | Instruction and study. |
Encyclopedias are among the most widely used reference sources and contain articles of varying lengths covering all fields of knowledge. Typically encyclopedias cover many topics but without going into a great deal of depth on any one thing. Encyclopedias are a good starting point for researching topics that you do not know much about or that are completely new to you. They can give you background information which can help when you move to more in-depth sources later. Specialized encyclopedias may cover just one field or even a sub-unit of that field. Subject encyclopedias can be consulted for detailed or technical information on a subject.
