I have a particular use case but am not 100% completely sure that Content Taxonomy is or can be designed to support it.

I have a preexisting (prior to installation of the module) custom content type. The content type is for adding a book to a database. The fields are basic CCK text fields with some using select lists. The fields include "Title", "ISBN", "Author", and "State." I have also created a taxonomy vocabulary with matching terms.

I would like to be able to increase the taxonomy vocabulary count when a new field is submitted. I would then display the count using the taxonomy menu module. Ideally, when a user submits the book form and completes all four fields the taxonomy menu should look as such:

______________
Title(1)
ISBN(1)
Author(1)
State(1)

When a use clicks on "Title(1)" for instance it would link to a page displaying a list of unique titles. I figure that when a new "Title" is added using the content form, the value will become an entry in "Title" vocabulary. Ideally, only UNIQUE entries will be counted and added. In order to eliminate duplicates I would use autocomplete (CCK autocomplete module http://drupal.org/project/cck_autocomplete) to help users avoid mistakenly entering duplicates despite being the same book ("The cat house" vs "The cathouse"). Is this the best method to avoid duplicates?

Is this something that can be done with the content taxonomy menu or taxonomy in general? Can someone please suggest a better more efficient way to do so if there is one?

I noted earlier that my current CCK form existed before installing the content taxonomy module, I have also created content using the form thus how would I implement the new content taxonomy field type into the preexisting form?

What I really want to do is to count the number of unique entries per CCK field and then be able to view a list of associated unique entries for each CCK field. Core Taxonomy and Content Taxonomy seem to be the only possible solution that I can think of though I am unsure on how to approach it/set it up. I somewhat feel that these modules may be a too complicated approach or not suitable at all.

Any suggestions greatly appreciated.
