I really enjoy reading ebooks. I read them on my laptop and on my phone. Bookworm is a site that moves your ebook library to the web, making it available from anywhere that you have a connection to said web. They support the open ePub format.

O’Reilly announced recently that they are now hosting Bookworm. ePub is composed of three open standards ( OPS, OPF and OCF ) that allow users a great amount of flexibility without any lock-in. Bookworm allows users to upload ePub files, read them on line from a pc or mobile device and also export them to mobile devices that support ePub. Bookworm can also export directly to Stanza. Once a user has uploaded their ePub books to Bookworm, they can track progress through them even across multiple devices.
