Where can i find books on theater of marcellus online?

i am doing a research paper that requires a bibliography using the MLA style but i dont have time to research at a library. Do anybody know any good sites? we are required to give the authors name and page number. im looking for a site where i can read books for free or download an e book and also if possible can somebody give me a little information on the theater of marcellus from a book they have read with the title of the book authors name and page number? I am not asking for someone to do my paper for me I just need a little help researching I am good at writting papers though.
