Users can now sort their To-Read Piles, read books, owned books, and tagged books by title (A-Z, Z-A), author (A-Z, Z-A), and publication date (Earliest first, Latest first).

With read books, you can also now see books in order of "Earliest read".

On all filter menus, including the Browse All Books one, you can also set a range for 'Original publication year'. In the screenshot below, I'm opting to see all books published from the year 2000, and then I'm sorting them with the earliest published first.
