{"value"=>"<p>This sub-series contains over 150 notebooks. The notebooks haphazardly kept, recorded material for future use, to make dances, write music and, later, books. When the notebooks were recycled, they were often cut up and pages were separated, lost, or interleaved in other notebooks. As a result, it is difficult to date the contents. The numbering system on the notebooks was already in place.</p>"}
