Zotero is "a free, easy-to-use tool to help you collect, organize, cite, and share research." It includes a number of tools (a standalone app, a browser plugin, several word-processor integrations) that amount to a complete bibliographic system.
Unlike most competing bibliographic software, Zotero is free, open-source software managed by an academic nonprofit. The service is free, but expanded storage capacity is available for a cost. It is in principle self-hostable, though the hosted service is affordable and convenient for most use-cases.
Create a class Group
Students and instructors can share a common bibliographic database around the themes of a course using Zotero's Groups functionality.
