On processing it was determined that the bulk of these files were last modified in 2006. Special Collections presume this is the date on which the files were copied to DVD 2019-PCMS-025-BD-004 for transfer to the Poetry Collection. File creation dates were estimated where file names included a date, however these dates may not be the actual date of file creation. Where no date is indicated in the file name, a creation date of "undated" is indicated. Access copies of these files are available for research use. During processing, formatting of the files may have been altered. The file format of the access copy may be different than the preservation copy. Refer to the collection processing note for additional information on format migration.
