"(...) a free, 'humble', modern, open-source, crowd-sourced replacement for the Dewey Decimal System. (...) The OSC will be: • Collaboratively written The OSC itself should be written socially--slowly, with great care and testing--but socially. See the Build the Open Shelves Classification group. • Collaboratively assigned As each level of OSC is proposed and ratified, members will be invited to catalog LibraryThing's books according to it. Using LibraryThing's fielded bibliographic wiki, Common Knowledge. And include: • Progressive development Written "level-by-level" (DDC's classes, divisions, etc.), in a process of discussion, schedule proposals, adoption of a tentative schedule, collaborative assignment of a large number of books, statistical testing, more discussion, revision and 'solidification'. • Public-library focus Academic collections, being larger, are less likely to change to a new system. Also, academic collections mostly use the Library of Congress System, which is already in the public domain. • Statistical testing As far as we are aware, no classification system has ever been tested statistically as it was built. Yet there are various interesting ways of doing just that. For example, it would be good to see how a proposed shelf-order matches up against other systems, like DDC, LCC, LCSH and tagging. If a statistical cluster in one of these systems ends up dispersed in OSC, why? (...) The OSC Project is a collaborative effort by LibraryThing members."
