Zotero
Collects web references, page snapshots and research documents with metadata, notes, collections and citation tools.

Meet Zotero
Zotero is a research reference manager that also works as a structured bookmarking and web-capture system. Its browser connectors collect resources into libraries where links can be organized with bibliographic metadata, notes, attachments and project collections.
Native clients cover Windows, macOS, Linux, iOS and Android, with a hosted web library available for synchronized records. The core software is free; paid storage concerns attachments, while optional user-operated file synchronization should not be mistaken for a fully self-hosted replacement of the Zotero service.
