I feel the professional cataloger's interface (codename Rancor) has gotten to the point where we can start thinking about integrating it into mainline Koha, and I've filed a bug ( http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=11559) with relevant information and a link to the codebase on Github. For those unfamiliar with the project, Rancor is a project I am working on for ByWater and a client of theirs. We're hoping to bring Koha a MARC editor that is powerful and intuitive for professional catalogers, who are poorly served by Koha's existing MARC editor. It has most of the core editing functionality nailed down, with some final refinements and improvements still needed to get it to production quality. Please try it out, and put any questions or comments on the bug. Thanks, -- Jesse Weaver
