@DedTV - Suggestion
Have you considered using a copy of the calibre database «metadata.db» as a resource to assist you in getting the job done.
The three tables I thought might be useful are books, tags and books_tags_link.
You can use the SQLite Database Browser to peruse the schema and contents, and execute SQL Commands
You may even be able to use a SQLite ODBC driver to hook the database into Access.
