The Otherwise Award (formerly James Tiptree, Jr. Literary Council Award) website, archiving 25 years of the award, with hundreds of works, and even more thousands of recommendations.
Using DataTables to show it all off in a searchable, filterable table; and marked up with Schema.org Microformats there and on all the annual award pages. Multiple templates for different sections; Ninja Forms for annual Recommendations submissions (then outputted in DataTables) and other contact forms (going off to SalesForce); Advanced Custom Fields for all award works data entry; improbable amounts of typography, masses of jQuery, responsive and accessible, and by far the largest project I’ve done.
