  • Simplified download links or instructions for Collections.
  • Simple Search is now in the top right corner of every page and works more like familiar search engines.
  • Searching by date is easier in Advanced Search for Collections.
  • Advanced Search options are all visible at once.
  • Collection detail pages include a tree of related Collections.
