Seeing as Jane Austen is always popular, it would be wonderful to have books that are related to her life up on Dailylit. Examples would include "Memoirs of Jane Austen" by James Edward Austen-Leigh, Jane Austen's Letters, etc.
You might want to add another way to organize all the books contained on the site: by length. Sometimes, I'm looking for a quick read (usually 60 parts or less) that I can get through in one day, some days I want to read something that will take me longer. Of course, 60-and-under-part books may take other readers more time, but organization of literature by length allows users to easily figure out how much time they're willing to commit.
