I'm confused. There was no ClarisWorks for the Apple II, only AppleWorks (only semi-related to the current AppleWorks for Mac & Windows) & AppleWorks GS for the IIgs. ClarisWorks started with version 1 for both Mac & Windows around the 1990. It could read Classic AppleWorks (Apple II) files & AppleWorks GS WP files. Even through AppleWorks 5 for the Mac could read these. AppleWorks 6 cannot.
If you're looking for Classic AppleWorks documentation, I think the best place to start would be a Google search for Apple II user groups. They do still exist.
