I'm using the hypertext field for book titles so they can be linked to the Internet. Now I'm coming across books that are not on the Internet, and thus, if used in a hypertext filed, it obviously leads to an error message for the end user. The only solution I can think of is creating just a plain text field specifically for those titles w/out an Internet presence. However, that will end up creating blank fields in the database, something I always hope to avoid. Any suggestions?
