The Cott Index Company has several indexing systems that are organized in one of these basic ways:<br>• Every surname is given a separate page with given names listed alphabetically.<br>• A key table provides a page number based on the first letter of the surname combined with the first letter of the given name<br>• The alphabet is divided into sections or letter groupings with tab sheets and indexes for each grouping.  
The Cott Index Company has many indexing systems, but they can be grouped into several groups:
 
==== Cott Key Table  ====
 
A key table appears at the top of every page.
 
==== Cottco Universal  ====
 
The alphabet is divided into units. A unit starts with a tab sheet showing the letter or the part of a letter contained in the unit. The unit next contains a sub-index sheet with page references for every combination of letters or commonly occurring surnames. The unit then contains the referenced pages.
 
==== Cott Family Name  ====
 
Every surname is given a separate page with given names listed alphabetically. A sub-index sheet at the beginning of each unit identifies the page numbers for the surnames.
 
==== Cott Guide Letter  ====
 
A key table provides a page number based on the first letter of the surname combined with the first letter of the given name.
