Literature Search
One query across PubMed, OpenAlex, Crossref and Semantic Scholar with duplicates merged.
One search, four sources
A single query is sent to PubMed, OpenAlex, Crossref and Semantic Scholar in parallel. Records describing the same work are merged into one entry that carries the metadata each source contributed, and results are ranked rather than returned as four separate lists.
What it is not
Literature Search is a discovery tool. It is not a systematic-review pipeline and does not claim exhaustive coverage or PRISMA compliance.
