Hi all, I run a small library and I want to allow OPAC users to browse our holdings by topic. Most of our holdings use the 653a MARC21 field as subject headings. I enabled the "OPAC Cloud" preference. Then I tried to build the tag database as instructed: export KOHA_CONF=/etc/koha/sites/biblioteko/koha-conf.xml; /usr/share/koha/bin/cronjobs/build_browser_and_cloud.pl -t 653a -c The command exited successfully, as far as I could tell. Now the OPAC shows a "Subject Cloud" link, but it only displays the following text: "Note: This feature only available to French catalogs where ISBD subjects have been populated, and an index built by separate script." According to HEA (https://hea.koha-community.org/systempreferences) at least 89 libraries around the world use this feature, and I can't believe they're all French language libraries. What are the exact requirements to have this working? Does any of you use this feature, and can guide me step by step? Rubén Fernández
