Knowledge Organization (JURN indexes open articles from 1974-2016, although this entails bringing in four years of paywall articles to 2020. The options were i) ‘all to 1999’ and no paywalled articles, or ii) ‘all to 2020’ and annoy searchers by including four years of paywalled articles. It was decided that it was worth some annoyance to get an extra 16 years of open content into JURN).
