Accruals and Additions
Addition to collection in October 2010, accession #2010.022. These materials were donated by EOL/MMM as part of their clean up of records held at off-site storage.
The collection was processed in February 2010. Materials in the Archives grouped together as the Weather Modification Collection were consolidated with materials labeled "NHRE." Records were then sorted into categories of like items and rehoused in acid-free folders. Paper clips and binder clips were removed. Oversize materials were flattened and stored in flat files. Additional materials were received in October 2010 and were added to the collection in December 2010.
