Researchers are welcome to use the information here as they wish.  They can view  and modify DVN from the download below.  All I require is that you reference its usage appropriately using any of  our several publications that have used DVN, for example:

Quinn J G & McConnell J (1996).  Irrelevant pictures in visual working memory.  Quarterly Journal of Experimental Psychology, 49A, 200-215.

or

McConnell J & Quinn JG (2004).  Complexity factors in visuo-spatial working memory.  Memory, 12 , 338-350.
