One way to organize items in Zotero is to create collections and sub-collections. Each item in Zotero can be in multiple collections and will always remain in your My Library collection.
You can use collections to organize items in whatever way makes sense to you, but here are some ideas:
- By research topic
- By theory used in the research
- To indicate status or next steps (e.g read, to-read)
- To indicate methodology used in the research
- By discipline, when you have works from a wide range of disciplinary backgrounds
