If your library wishes to use added content provided by Obalkyknih.cz, a service based in the Czech Republic, you have to create an Obalkyknih.cz account. Please note that the interface is only available in Czech. After logging in your Obalkyknih.cz account, you have to add your IP address and Evergreen server address to your account settings. (In case each library uses an address of its own, all of these addresses have to be added.)

Set obalkyknih_cz.enabled to true in /openils/var/templates/opac/parts/config.tt2:

obalkyknih_cz.enabled = 'true';

Enable added content from Obalkyknih.cz in /openils/conf/opensrf.xml configuration file (and – at the same time – disable added content from Open Library, i.e., Evergreen’s default added content provider):

<!-- <module>OpenILS::WWW::AddedContent::OpenLibrary</module> -->
<module>OpenILS::WWW::AddedContent::ObalkyKnih</module>

Using default settings for Obalkyknih.cz means all types of added content from Obalkyknih.cz are visible in your online catalog. If the module is enabled, book covers are always displayed. Other types of added content (summaries, ratings or tables of contents) can be:
