[SalesForce] how can I report on report types in salesforce

I have accumulated scores of custom reports types within my org and some of them I think are obsolete, therefore I would like to remove them, however, in the interest of integrity, I would like to make sure that no reports are based on the report type that I want to delete, therefore I am looking for a way of reporting of the reports by report type so that I can find out this information.

You can create a custom report type of the report object that will include the report type as a field - then create a report using this custom report type. This report will be able to list the report types of all the reports.
