Without knowing exactly what you currently have and what is the objective, on first glance it looks like the list of attributes you have provided belong to more tha one enyity which would suggest that he table needs normalising.

For instance "Date of Work" surely this is an attribute belonging to a piece of work not the Author, unless of course you are saying an author can only produce a single piece of work, similarly the ISSN you mention I think should be International Standard Stationary Number which would be the attribute of a book not the Author.

Also you have a column named Dates which suggests you will be storing more than one date surely poor practice also.
