Downloads

The Islandora Internet Archive Bookreader module can be found on the Release Notes and Downloads page.

  • If 'git' is installed on your server, you can navigate to your Drupal installation's sites/all/libraries folder and run "git clone gitclone 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'.

After you install and enable the module, go to Administration > Islandora > Solution pack configuration > Book solution pack (admin/islandora/solution_pack_config/book).

  1. Under Book Viewers, select Internet Archive BookReader. 
  2. Under Page Viewers, select OpenSeaDragon.
  3. Click Save Configuration.
