Browse Research Fields
How our browsing hierarchy works: Paperzilla groups every paper into one of four broad scientific domains (Health Sciences, Life Sciences, Physical Sciences, and Social Sciences) and then into 5-10 finer-grained research fields inside each domain. The structure mirrors the OpenAlex ontology, but we refine it with AI-driven citation networks so related work surfaces side-by-side. Browsing this hierarchy lets you jump straight from a discipline overview to seminal papers - even when exact keywords differ - making research-paper discovery faster and more serendipitous.
