Category

Research

Research resources should help people compare sources, verify claims, or summarize a topic quickly.

Editorial note

We prefer tools that make evidence easier to inspect, not harder.

What we look for

Search tools, citation helpers, databases, and comparison pages with real context.

Best for

writers, analysts, and anyone checking facts before acting

Useful pages in this category should explain the job they solve quickly and link to a trustworthy destination.

Use it when

  • Check a claim against a source instead of relying on memory.
  • Compare several references before making a conclusion.
  • Pull together enough context to decide what is worth reading fully.

Not a fit

It is a poor fit for sources that hide provenance, cite nothing, or only summarize themselves.
