Decision aids

Read the direction of a publication relationship

Crossref relationships have a direction: described and linked objects play different roles. Read the relationship before replacing a reference.

  1. Identify the described object
  2. Read the relationship
  3. Compare the cited passage

SituationWhat changesUseful check
isPreprintOf / hasPreprintLinks a preprint and associated publication in opposite directions.Check which document was actually read.
isVersionOf / hasVersionDeclares a version relationship.Compare tables and conclusions; the link does not mean identical text.
isReviewOf / hasReviewLinks a review and its subject.Read the review and its scope before concluding.

A working DOI identifies a resource without awarding a quality label. A missing metadata relationship does not establish that works are unrelated. Retain the title, version and passage used.

From a resource to usable evidence

Keep a verification trail behind an answer

Define the expected result before choosing a search engine, calculator or assistant. Useful answers remain connected to documents you opened and explicit assumptions.

Cite the version you actually read

A version suffix distinguishes successive states of an arXiv submission.

A question to resolve: Your notes concern v1, but the unversioned link now opens v3. What should you retain?

A record worth keeping

Keep the question, date, opened sources, relevant passages and unconfirmed points. Remove confidential information before submitting it to an external tool.

Move from a summary to a checked source

A summary seems useful. Reconstruct the chain connecting the claim to a document and its supporting passage.

  1. Identify the work

    Record title, authors, date and identifier. Distinguish automatic summaries from author-written text.

  2. Read the right version

    Check preprint, published paper or new version. Record relevant changes.

  3. Examine the passage

    Read method, result and nearby limitations. Keep conditions associated with the conclusion.

Useful output

A claim accompanied by an identified document, version and checked passage.

A citation in an automatic answer does not establish that it supports the claim.

Is an answer with links verified?

Links make checking possible. Open them and confirm that they support the claims, period and context.

Can a generated answer serve as a factual source?

For verifiable facts, cite the original document you consulted. Use the assistant for preparation and preserve remaining uncertainties.

Is a generated synthesis the search method?

No. Keep executed queries and decisions, then verify original documents.

Which website for which need?

Four concrete starting points.

These resources answer different questions. Match one to your task, then make the suggested check before relying on its result.

Google Scholar

Find a scholarly publication

Search by title, author and bibliographic variants.

Check first Open the publisher or repository to check the text’s version.

Find Google Scholar →
Semantic Scholar

Explore studies related to a paper

Follow authors, citations and topics around a publication.

Check first Read the studies before inferring a consensus.

Find Semantic Scholar →
Brave Search

Compare web search results

Use another search index to find sources absent from an initial list.

Check first Compare domains and distinguish results from ads.

ChatGPT

Explore a question with an AI assistant

Ask for assumptions and a research plan.

Check first Verify important claims against an accessible, dated source.

Similar names, different purposes

Choose by the document or action you need.

These comparisons show when two resources in the same subject answer different questions.

Preprint or generated synthesis?

arXiv hosts versions of research papers; Consensus helps explore studies around a question. Open the papers before accepting a conclusion and check their publication status.

Computed result or written explanation?

WolframAlpha can explore calculations and conversions with parameters; a conversational assistant can help frame and explain. In both cases, inspect assumptions and data sources.

From a category
to the right destination.

The portal gives you context before the external click. Current conditions and sensitive instructions must still be confirmed with the destination publisher.

  1. 01
    Choose a subject

    Start with the category that matches your practical need rather than the name of a platform.

  2. 02
    Read the record

    Use the publisher, description, country and topic tags to understand what the resource covers.

  3. 03
    Check the destination

    Confirm that the external domain matches the publisher and service you intended to reach.

  4. 04
    Verify changing details

    Review current dates, prices, availability, terms and sensitive instructions on the destination website.

Useful scope.
Clear limits.

What is included in the World Web Certified directory?

The directory contains 232 useful starting-point websites across 13 subjects, including public services, health, education, media, culture, search, digital tools, travel, consumer information, science and sport.

Are directory entries certifications or rankings?

No. Inclusion is an editorial orientation choice, not a technical certification, commercial ranking or guarantee covering every page and service on the external website.

Are the individual records available in English?

Yes. Every directory record has an English page with a description, publisher, official destination, a specific use case and practical checks. Use the language menu to open its French counterpart.

How should I verify an important destination?

Check the domain, publisher and purpose described in the record, then confirm current terms, dates and sensitive information on the destination website before acting.

How can I report an error in a record?

Use the Contact page and provide the relevant URL, the inaccurate passage and a supporting source when possible.
