I recommend http://www.academia.edu . A social network sites of scholars. Researchers, including historians, upload their articles/book chapters/entire books to make them public.
If you, for example, enter 'Roman army' you get access to more than 600 papers: http://www.academia.edu/Documents/in/Roman_Army
