Explore the Harvard University Press website to understand how users can find books that are currently available for purchase, specifically by using filtering or sorting options. Additionally, identify if there's a way to view only 'Hardcover' books within the 'History' subject category. Finally, confirm if the 'SUMMER SALE' is still active and what discount code is required.
Navigate to the Harvard University Press homepage. Click on the 'Books' button (ID 16) to expand the dropdown menu. Click on the 'History' link (ID 36) under the 'Subjects' category. On the 'History' books page, locate and click on the 'Filter by Format' button (ID 129). Select 'Hardcover' from the format options to apply the filter. Observe if the list of books changes to reflect only hardcover editions. Examine the page for any visible indicators or options to filter books by publication status (e.g., 'forthcoming' vs. 'available'). Look for the 'SUMMER SALE' banner or any promotional text on the page to confirm its activity and identify the discount code. State whether a filter for 'available' books was found, confirm if filtering by 'Hardcover' worked, and provide the details of the 'SUMMER SALE'.
