When Henry Lowood, curator of the History of Science and Technology Collections at Stanford University, started preserving video games and video-game artifacts in 1998 he thought it was closer to professional oblivion than a bold new move into the future.

In just a few years, however, Mr. Lowood’s notion that video games were something with a history worth preserving and a culture worth studying has gone from absurd to worthy of consideration by the Library of Congress.

On Thursday at the annual Game Developers Conference in San Francisco, Mr. Lowood announced a game canon, an idea that grew out of a proposal submitted to the Library of Congress in September 2006 by a consortium made up of Stanford, the University of Maryland and the University of Illinois.

“Creating this list is an assertion that digital games have a cultural significance and a historical significance,” Mr. Lowood said in an interview. And if that is acknowledged, he said, “maybe we should do something about preserving them.”
