Hi In our library we are using Koha 18.05.03 on Debian GNU/Linux 8. According to https://bywatersolutions.com/education/overdrive-integration-in-koha Overdrive is integrated within Koha. From Overdrive we have got several bits of information but in Koha 18.05 we have only the following available system preferences: * OverDriveCirculation * OverDriveClientKey * OverDriveClientSecret * OverDriveLibraryID Filling these in indeed shows the new tab "OverDrive account" in the OPAC user account, but then an "Internal Server Error": Could not compile /usr/share/koha/opac/cgi-bin/opac/external/overdrive/auth.pl: Can't locate WebService/ILS/OverDrive/Patron.pm in @INC (you may need to install the WebService::ILS::OverDrive::Patron module) (@INC contains: /usr/share/koha/lib /usr/share/koha/installer /usr/share/koha/lib/installer /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.20.2 /usr/local/share/perl/5.20.2 /usr/lib/x86_64-linux-gnu/perl5/5.20 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.20 /usr/share/perl/5.20 /usr/local/lib/site_perl . /var/lib/koha/sbtreu/plugins) at /usr/share/koha/lib/Koha/ExternalContent/OverDrive.pm line 24.

Compilation failed in require at /usr/share/koha/opac/cgi-bin/opac/external/overdrive/auth.pl line 27. BEGIN failed--compilation aborted at /usr/share/koha/opac/cgi-bin/opac/external/overdrive/auth.pl line 27. Does anyone know the solution to this? I see in later versions of Koha there are more preferences: * OverDriveAuthName * OverDriveUsername * OverDrivePasswordRequired * OverDriveWebsiteID We have the necessary bits of information from Overdrive but we can't fill them in in Koha 18.05. Does this mean the Overdrive integration in Koha 18.05 is not functional and we will have to update to a newer Koha version?
