In 2023 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.
