The new epub module for Drupal 7 provides displays for file entity and file fields and enables users to read epub/ibooks files inside their browsers like pdf module.
Use this module with apachesolr_file (recommend with file_entity 7.x-2.x), you can build your owned online library.
"ePub default" display uses iframe to wrap xhtml files extracted from epub package
"ePub cover image" display shows the cover image inside epub file (A cover image is not required according to the ePub standard)
TODO: add js epub reader in the future and need help to make something like Readium work on server side
6.x-1.x
The ePub module allows site administrators to enable other users to download the ePub version of the book contents available on the website.
The Node Menu Parent module extends the "default menu for content" setting provided by the core menu module by allowing a specific menu item to be selected (not just a top-level menu) per content type.
Example
Imagine we're creating a site for a business that will have a section describing the products they offer. We've got the core content types, Page and Story, and we've added our own content type called Product. Then we add a few pages under the Primary links menu, like so:
<Primary links>
Products
Support
About Us
Now say we've decided that every product should have a menu item under Products. However, core Drupal's menu settings only let us choose a global default menu for content, such as Primary links. That means when we go to create a Product, the "Parent item" dropdown under "Menu settings" defaults to Primary links so every time we create a product we have to manually select Products as the parent item. This is tedious, easy to forget, and unnecessary extra clicking.
