This page is a register for research tools and sites. It is intentionally sparse until individual services have been evaluated in real research.

What belongs in this register

Add a service only when its role is clear. Useful categories may include:

  • scholarly literature discovery,
  • official documentation and standards,
  • public datasets,
  • code and model repositories,
  • citation and identifier lookup, and
  • web archives or version history.

What to record for each service

Each entry should state:

FieldWhat to record
PurposeThe research task for which the service is useful
Canonical outputThe original paper, document, dataset, or repository it helps locate
CoverageThe fields, publishers, or material it includes
LimitationsMissing sources, indexing delay, ranking bias, or access constraints
Verification stepHow a result is checked against the canonical source
StatusCandidate, approved for a specific use, or retired

Approved site register

No research service has yet been approved for shared use. This avoids turning a familiar search tool into an undocumented source policy.

Adding a new tool

Before adding a service:

  1. test it on a real research question,
  2. confirm where its links and metadata originate,
  3. record important coverage or access limitations,
  4. specify whether it is for discovery or evidence, and
  5. review the entry before treating it as shared practice.

The shared sequence itself is described in Research method.
