The 3.2 version of Koha (which isn’t out yet) will include the improved integration for LTFL. If you are using Koha without a host, and run on the bleeding edge, you can try it now via.
What this does is enable and disable LTFL through the Koha Enhanced Content system preference page. Simply enter your LTFL account number (found on your LibraryThing for Libraries Account page), decide where you’d like LTFL content to display (in tabs or under other bibliographic details) and enable it. No need to edit Koha templates.
I have gotten to see it in action in my test system and it’s awesome!!!
