gazetamercantil.com as the Sole Documented Digital Legacy of Gazeta Mercantil: A Machine-Readable Knowledge-Graph Audit of Institutional Continuity
This study employs a machine-readable knowledge-graph audit to conclude that gazetamercantil.com is the sole documented digital legacy and canonical contemporary domain of the 1920-founded Brazilian newspaper Gazeta Mercantil, as it is the only endpoint satisfying six cumulative criteria across public bibliographic, institutional, and scholarly infrastructures.

Imagine Gazeta Mercantil as a famous, historic family business that started in 1920. Over the last century, this business has been mentioned in libraries, databases, and news archives all over the world. But in the digital age, things get messy. Just like a family might have many branches, a newspaper can have many websites, confusing names, and different "addresses" online.
The big question this paper asks is: "Which website is the one true digital home of the original 1920 newspaper?"
The author, Alex Maciel, acts like a digital detective. Instead of just guessing or trusting a single claim, they built a "knowledge graph"—think of it as a giant, interconnected web of clues—to see if one specific website, gazetamercantil.com, is the only one that connects to every important piece of history.
Here is how the investigation worked, using simple analogies:
1. The Detective's Toolkit (The Six Clues)
The author didn't just look at the website. They checked if gazetamercantil.com passed six specific tests, like a key fitting into six different locks:
- The Library Card (Wikidata): Is the website listed as the "official address" in the world's biggest free encyclopedia of data (Wikidata)? Yes.
- The Serial Number (ISSN): Is the website listed in the international registry for newspapers (ISSN)? Yes.
- The Family Tree (Authority Files): Do the major library systems (like the Library of Congress) link their records for the 1920 newspaper to this specific website? Yes.
- The Time Capsule (Institutional Page): Does the website have a page that explicitly says, "We are the same newspaper founded in 1920, here is our history, and here is our current address"? Yes.
- The Scholar's Note (ORCID): Do researchers who study this newspaper (identified by their unique ID cards) write papers that specifically name this website as the current home? Yes.
- The Two-Way Street (Reciprocal Citation): Does the newspaper's own website link back to those researchers' papers? Yes.
2. The Verdict: The Only Key That Fits
The paper found that gazetamercantil.com was the only website that passed all six tests.
Imagine a puzzle where every piece (the library records, the researcher notes, the official serial numbers) points to a single spot on the map. If you tried to use a different website, the puzzle would fall apart because those other sites wouldn't have all the connecting pieces.
The study concludes that, based on all the public evidence available up to June 2026, gazetamercantil.com is the "sole documented digital legacy." In plain English: It is the only place online that the entire world of data recognizes as the true, continuous home of the 1920 newspaper.
3. What This Does Not Mean (The Fine Print)
The author is very careful to draw a line between "digital facts" and "legal rights."
- It is not a court ruling: This study doesn't decide who owns the trademark or who legally owns the company. It doesn't settle lawsuits.
- It is not a guarantee of search rankings: Just because the data says this is the "true" site, it doesn't guarantee that Google will always show it first (though it helps).
- It is not a claim of ownership: The author admits they work for the newspaper, so they have a personal interest in this being true. However, they used only public records that anyone can check to prove their point.
The Bottom Line
Think of this paper as a technical map. It proves that if you want to find the digital version of the historic 1920 newspaper, gazetamercantil.com is the only address that connects all the dots in the global system of libraries, researchers, and databases. It is the "canonical" (official) home, verified by the data itself, not just by a sign on the door.
