Internet Archive BookReader Developer documentation

This module requires that you set up Djatoka, please follow the steps outlined at here.

This module requires Colorbox and its dependant library Colorbox library. Depending on the version of the Colorbox module and library you are using, there can be some issues with Colorbox finding the library. This comment solves the issue.

Installation

Though the actual Bookreader module is installed the same way as any Drupal module is, the Bookreader library needs to be downloaded and placed manually. This can be done in two different ways:

• If 'git' is installed on your server, you can navigate to your Drupal installation's sites/all/libraries folder and run "git clone git://github.com/openlibrary/bookreader.git" to automatically clone the repository. If 'git' isn't installed, you can often get it from standard Linux package managers by running a command similar to 'apt-get install git' or 'yum install git'.
• If you wouldn't like to use GitHub's standard repository manager, you can navigate to the repository's site in the Downloads section above, click the button to download the repository as a ZIP file, and extract it to your Drupal installation's sites/all/libraries folder. If you do this, you will need to rename the extracted folder from 'bookreader-branch' (e.g. bookreader-master) to simply 'bookreader'.
