In the Enhanced content preferences chapter, under LibraryThing (https://koha-community.org/manual/latest/en/html/enhancedcontentpreferences.html#librarything) There is a link to what was presumably a section about Koha in a wiki. http://www.librarything.com/wiki/index.php/Koha However, this does not exist anymore. I did not research if a wiki still existed and if so, if there is a section about Koha.
