Is there a web/cloud application that allow to build own ebook library?

I looked at Google Books, Amazon Kindle ...... they only support their own ebook library. What I want is a central place where I can

1, Store my own ebook library, from Amazon, and any other source;
2, Upload my own ebooks, PDFs, Word documents etc - this is the biggest challenge;
3, Read them on my mobile device and online.

Is there such available or something similar?

Thanks
