Sources, Standards & Corrections
How EliExplains.org chooses sources, writes lessons, and fixes mistakes.
Source selection
EliExplains.org is founded, owned, and operated by Vansh Tiwari as part of the Open Mosaic Education Foundation educational initiative. See Ownership and operation for its current status.
Lessons are researched from primary and authoritative sources first: government and intergovernmental publications, peer-reviewed and open-access research, university materials, and openly licensed educational resources. Every source used in a lesson is recorded in an internal registry with its URL, provider, license status, and the date it was checked, and each published lesson will display its sources.
Original explanations, grounded in sources
The library has two lineages, and every lesson shows which sources ground it. Original EliExplains lessons are written from sources without republishing their prose: we read, verify, and write our own college-level and plain-language explanations. The science and health library (biology, chemistry, physics, anatomy and physiology, nursing, allied-health and exam-prep subjects) was built as a study companion to openly licensed textbooks — chiefly OpenStax titles published under Creative Commons Attribution (CC BY 4.0) — and to public references such as government health agencies. Those lessons follow the textbook’s chapter structure, are written as study guides rather than copies, and link the textbook or reference they accompany (see Copyright & Licensing). Original vocabulary libraries (for example the Security+, Network+ and Linux command glossaries) are written in-house in a fixed four-part format — term, definition, a plain-language “Eli explains” version and an everyday example — and follow the public exam objectives or command documentation they cover.
Which sources the health and science library reaches for. Where a choice exists, material is grounded in openly licensed textbooks (chiefly OpenStax), government health agencies and their reference services (the National Library of Medicine and PubMed Central, MedlinePlus, the CDC, the National Cancer Institute, HHS, CMS, the National Human Genome Research Institute, OSHA), international public-health bodies, standards and reference databases such as the NIST Chemistry WebBook, and the professional associations that publish the requirements for a credential. Naming a source here means it is preferred when a citation is chosen; it does not mean every page carries one, and none of these organizations endorses EliExplains.org or has any connection to it. This material has been checked against those sources, not by a clinician — see the Educational Disclaimer.
The New Jersey law library came from EliExplains Law, our sister project, and follows the method that project publishes: a statement of New Jersey law should trace to the constitution, a statute, a regulation, a court rule or a decided case, and the lesson cites it and links an official source where a stable one exists. Its sources are the New Jersey Courts, the New Jersey Legislature, the New Jersey Board of Bar Examiners and the National Conference of Bar Examiners; those bodies change dates, fees and requirements without notice, so anything you are planning around should be confirmed with them directly. It is written by a non-lawyer as educational material and its case examples are summaries rather than certified reports — read the cited opinion, not the summary, before relying on a case. See the Educational Disclaimer for what this library is not.
Review before publication
Original lessons go through source-rights, factual, and editorial review before publication. The science and health library was imported in one audited migration: every record was checked for structure, integrity, duplicate consolidation, answer keys and source links, and material that did not meet those checks (placeholder outlines, index files, unresolved records) was withheld rather than published. Individual lessons in that library have not each been re-verified by an editor; treat them as study guides, check important facts against the linked textbook, and tell us when something is wrong.
Corrections
When an error is found, we fix the lesson and update its review date. If a correction is material, the lesson will say so. Spotted a mistake? Tell us the page, the statement in question, and if possible the source that contradicts it.
