The Instruments of the Atlas

315 laws, 864 regulations, 125 guidelines and 1,373 treaties, article by article

This page opens every instrument of the Atlas, one by one, at the text its map was built from. A law, a regulation, a guideline or a treaty is shown as a consolidated document, with its books, titles, chapters and sections as headings, its articles as paragraphs and its tables as tables, so that it can be read from the first line to the last or entered at any article.

The search box finds an instrument by name or by abbreviation, and it ignores accents and case, so that constitucion finds the Constitution. The buttons above the table keep one collection only, a click on a column heading sorts the table by it and a second click reverses the order, and a name opens the instrument. The outline on the left follows the document, a fold hides the contents of a title or a chapter, and a click on any entry goes to that place.

An article, an introduction, a table or the preamble is what the Atlas calls an excerpt, the piece of text that it compares with the rest of the corpus. A heading and a transitory article say little about how two instruments relate, so they are left out, and the remaining ones are called compared excerpts. Each of them is marked in the margin of the document with a thin rule and the word Compared, and it carries a Nearest texts line. Opening it lists the five closest texts that live in other instruments, each with its similarity as the Qwen3 Embedding 4B model measures it, which is the 4B option of the Atlas. A text that several instruments share appears once, with the others named under it. Following a link opens that other instrument at the excerpt in question, highlighted, and the browser’s back button returns to where the reading was.

Every instrument and every excerpt has an address, so that a link can point at it. An address such as instruments.html?c=leyes&k=ccf#art_1 opens the Federal Civil Code at its first article.

The text is the consolidated snapshot of the Supreme Court of Justice of the Nation from which the vectors were built, and its date is shown under the name of each instrument. The documents themselves are not part of the site’s source, being the atlas-instruments release of the repository, which the publishing workflow downloads and unpacks next to this page, and the page fetches one file only when an instrument is opened. The Diario Oficial de la Federación remains the official source of legal text.
