Wikipedia remains the world"s biggest information resource used by communities of volunteers. Most of the other encyclopedic resources are smaller in size but, compared to Wikipedia, they are designed for specific areas of expertise and, typically, are maintained by non-for-profit organizations or persons with significant knowledge of specific topics. In many cases, they also have alternative publication policies for accepting online content, as well as the dispute resolution policies which have become increasingly important for the resources edited by large communities of experts.
The new article with the title Top 5 Wikipedia alternatives you should know about in 2023 compares Wikipedia to several alternative online encyclopedias. It only touches wiki-style encyclopedias with free content, i.e. licensed under the Creative Commons Attribution-Share-Alike License or similar licenses. It does not discuss, for example, Britannica, which is another great resource, but it has a more restrictive license (plus it is behind a paywall).
