Our Take
One of the best free research tools nobody talks about. Killer feature: treats preprints as first-class citizens, auto-linked to published versions. A default tab for life-sciences researchers. Limits: life-sciences only; thinner citation tooling.
Power Tips
- SRC:PPR for preprints only
- the “Journal published” sub-filter
- HAS_PUBLISHED_VERSION:Y
- early-warning alerts (all Issue 4).
