Editorial Policy

Who writes the guides

Lelfy's editorial desk has 15 members. They are former classroom teachers and former practitioners. Their former fields include analytical chemistry, systems administration, economic analysis, hydrology, careers counselling and software engineering. The desk writes across Mathematics, Physics, Chemistry, Biology, Geography, History, Economics, Business, Marketing and Computer Science.

The library contains 227 topic guides, ten subject hubs, about 75 articles and a free culture-fair intelligence test. Every guide and article carries the name of the person who wrote it. The name identifies the member of the desk responsible for that piece of work. No guide or article is presented without its writer's name.

How a guide is made

A subject has a lead from the editorial desk. The guide is written by a named member of the desk. It explains how the subject works. It does not depend on figures that the desk cannot stand behind. It does not link to sources that cannot be checked.

Every member of the desk works to one house style guide. The style guide fixes the common editorial approach used across the guides. It is why guides written by different members read consistently. The editor in chief owns the style guide and the process used to review work before publication.

This process applies across all ten school subjects. The subject changes, but the house style does not. A Mathematics guide and a History guide are written by people working from the same editorial rules. The writer remains named on each guide and article.

The second read before publication

Every guide and article has a second read before it is published. The second reader is another person on the editorial desk. The writer and the second reader are not presented as the same person. Both names appear on the published work.

The second read sits within the review process owned by the editor in chief. It applies to every guide and every article. The page records who wrote the material and who read it before publication. The shared house style guide gives the desk one editorial basis for its work.

Questions and corrections

Questions and reports of errors go to [email protected]. A reported error is checked against the guide concerned. If the guide is wrong, the error is corrected. Lelfy does not promise a response time for email.

The check concerns the reported point and the guide in which it appears. A correction follows when that check shows that the published material is wrong. The same address can be used for a question about Lelfy's material.

Advertising and paid material

Lelfy carries no advertising. It publishes no sponsored articles and uses no affiliate links. It accepts no paid placement of any kind. Nothing on the site is bought. These rules apply to guides, articles, subject hubs and the free culture-fair intelligence test.

The absence of paid material means a place in the library is not sold. A guide is not sponsored, and an article is not placed for payment. Links do not earn affiliate payments. The editorial desk produces the site's educational material without these commercial arrangements.

Information about readers

Reading Lelfy requires no account, sign up or newsletter. Lelfy runs no third party analytics and no tag manager. It sets no advertising cookies. A person can read the guides and articles without creating a Lelfy account or joining an email list.

Lelfy counts page views with software that it hosts itself. This page view count is the stated measure of use. It is not run through third party analytics or a tag manager. The site does not add advertising cookies for this purpose.

Limits of the material

Lelfy is educational material. Its guides and articles explain school subjects and related topics. They are not medical, legal or financial advice. The material does not replace advice from a person qualified to deal with an actual medical, legal or financial decision.

A person facing a real decision in any of those areas should speak to a qualified professional. This limit applies even when a guide or article helps explain a relevant idea. The material can explain how something works, but it is not professional advice for an individual decision.
