During Robert’s lifetime, he assembled an extensive digital database that is stored on a hard drive compatible with Windows and Mac iOS systems.
This database contains a vast amount of information, including acquisition lists with thorough annotations of his research, notes, and historical context related to Dracula and vampirism. Furthermore, it includes drafts of plays and novels, PDF copies of rare books, historical images, personal writings, contact directories, and correspondence with scholars, collectors, and authors. This database is of significance for future researchers.
