BUENOS AIRES — The Buenos Aires Herald opened its doors nearly 141 years ago, but became legendary by exposing forced disappearances during the 1976-83 military dictatorship, a chapter of Argentina’s history that other papers whitewashed.

Late last month, the English-language paper folded, a victim not only of technological changes that have made it difficult for small newspapers across the world to stay afloat, but also because of neglect by a string of owners who seemed to care little about the publication’s history and how it could adapt to the modern world.

When the Herald announced it would cease operation, the paper had turned into a shadow of its former self, having gone weekly in October with a bare-bones staff. Yet that did not stop the tributes from pouring across social media, or discourage journalists from writing obituaries to the small paper that increasingly seemed a relic of a bygone era.

In Buenos Aires, one newspaper dedicated a seven-page supplement to the Herald. Another local paper asked three former editors to write about their experiences at the Herald, and a former staff member eloquently wrote a back page column about the paper’s storied history for a weekly.
