I hold an MLIS and have contributed records to WorldCat in the past (I now work outside the library business).
I can't speak to any of the copyright technicalities, but I can confirm that the MARC records are generally created and enhanced by the employees of participating institutions. The idea is that if the book has already been accessioned by another member and they've uploaded the record, you can use most or all of their work (descriptive work, subject headings, classification) and get your new acquisitions out on the shelf faster. If something's wrong or missing, you fix it and share it back, along with new records you create. (Non-participating institutions can get canned MARC records from the Library of Congress and other libraries that make their OPACs available over Z39.50, but the quantity and quality on WorldCat are better)
I always assumed that the participating institutions are either assigning the copyrights or, more likely, granting OCLC an assignable perpetual license.
