Source directory

Each article has its own source list. The machine-readable directory keeps the article and the evidence together.

Browse the directory

The guide JSON lists guide and comparison articles with their canonical URLs, source-read dates, summaries and cited source URLs. Those citations include official documentation and community discussions; check the publisher and source type before relying on a claim. The plain-text collection includes article text and references. Use the topic hubs to browse by subject.

What an official source establishes

A vendor can establish its published feature, dimensions or terms. It cannot independently establish that its product is fastest, most comfortable or most reliable. We do not convert vendor marketing claims into test results. Read the research method for the difference between a cited fact and an editorial fit judgment.

When a source changes

Plan labels, model revisions and regional specifications change. The date on an article records when the cited material was read, not continuous monitoring. Please report a changed source through the corrections page, identifying the article and the exact claim.
