I have been using Zotero every day for more than two decades and somehow it hasn’t cross my mind. You may be on to something.
Zotero supports public and private shared bibliographies that you can subscribe to through the client or their web interface. Each entry contains the bibliographical details, notes attachments, file attachments and links to local files. It also captures webpages and metadata through the browser addon. The local database can be backed up and, if self-hosted, you have control. The best part is that academic researchers will be familiar with the software and process. One downside is that the cached file is not independently archived so it could be tampered with. Thanks for the idea.
Thanks for doingthe digging. An archivist may know something more. Or the archive.is people.
