The current CCS data was pulled from excel sheets that were available on the old CCS Data site.  Some of it may be dated, some blanks listed may not even be in production anymore.  If you find some of the data incorrect, use the contact us menu item to drop me a line.   If you have data to add you can create an account by clicking the Member Login button on any page and create an account.  Once your account is verified when you hover over the CC Database menu item you should see another item appear that says add, click that and you can now add a new entry into the database.

The search/filter on the CC Database page can filter by any field, you can also click the column heading to sort by that column.  If you have an idea for a feature, drop me a line and I will consider it.
