In order to earn your Champion through straight literature, you must have earned the breed standard requirement in Literature CACIBs. For example: if the breed standard requires you to earn 2 CACIBs for Champion, then for Literature Champion you must have 2 LCACIBs. Your LCACIB can still earn you a regular Champion, but it may only award you one or the other. You cannot use the same two LCACIBs for Literature Champion and Regular Champion, but you may use LCACIBs to earn a regular Championship.
The Literature Working Champion will work the same way as the Conformation Champion above. It will require the breed standard amount of CACITs in the form of LCACITs. The same rule also applies where you may use LCACITs to earn you a normal Working Champion title, but you cannot use the same LCACITs for a Literature Working Champion.
In UaKU a Versatile Champion is a dog who has achieved both CACIBs and CACITs. For a Literature variation of this championship, you will need 2 LCACIBs and 1 LCACIT or what the breed standard lists for Champion requirements.
To reach a Literature Grand Champion in any of the categories above (Conformation, Working, Versatile), you must earn double the requirements as per the breed standard. If the breed standard calls for 2 CACIBs to reach the champion, then it will be 4 CACIBs to reach the grand champion.
