The Memento project wants to give browsers a ‘time-travel’ mode. Currently, the only way to find these pages is the Wayback Machine. According to an interview with Memento’s Herbert Van de Sompel, the mission of this project is to make it far easier for users to find older pages without having to go through the hassle of putting the right URL into the Wayback Machine’s search engine.

HTTP Content Negotiation

To do this, Van de Sompel and his colleagues are exploiting a feature in the HTTP content negotiation specs that allows them to add date-and-time negotiation to the standard negotiations that already happen whenever your browser connects to a web server. Instead of just asking for the current page, a Memento-enabled browser can also ask for an older version of that page. Some servers and content management systems already offer this feature and the Memento project has developed a demo that shows how this feature would look. According to Van de Sompel, it only takes four extra lines of codes in Apache to make this work.

While it is relatively easy for browsers to ask for an older version of a web page, content owners would have to store these older versions of their sites on their servers as well. With static sites, this is easy to do, but today’s highly dynamic web doesn’t make it easy to create an archival version of every page.

 There is a cliche that many people often share about history, and how it is written by the victors. The conquerors across the world, for the most part, are the ones who transcribed the history for others to read. We have terms like "revisionist history" to account for the fact that we realize the truth may be quite a bit grayer than those historical accounts we read lead us to believe. And it is often the sole dissenting voice that points us toward what the true history may be – some in between version where the good guys are perhaps not quite so good, and the bad guys not so bad.

It is easy to think of these shades of history while traveling in Greece (where I spent the past week), because the evidence of this is all around. From the city of Acropolis high over Athens to the softly smoldering volcanic remains in the caldera of Santorini. What was once religion is now called mythology, a sign perhaps that our religion of today may befall the same fate. Amongst those ruins of temples and palaces, there is the beautifully frustrating knowledge that we will probably never know what these really looked like or how these people truly lived.

The history today will be different. With technology and social media, we have the effortless ability to capture our individual truth and experience in minute detail and save it on shared servers for the world to access hundreds or thousands of years from now. Ironically, this fact may make the study of history that much more complicated, as historians in the future will have many versions of truth to study and contrast. Rather than piecing this history together through buried bone fragments and stones with the rare written account as they have done for many years, they will do it through compiling and sorting data, analyzing imagery and watching video.

Combined with global historical initiatives such as the Internet Archive and Google Earth, the portrait of our world as it stands today will be far more complete and multi-experienced for historians of the future than any other age that has come before. For those of us who write blogs or upload photos, the scope of our actions are easy to forget or minimalize. But we are the new historians of our time and our content will one day be history – and probably for more than just ourselves. It’s a humbling to imagine your own words on this scale … particularly when you think of who could be reading them a long time from now.

Last fall under a proposed settlement between Google and the Authors Guild and the Association of American Publishers, Google agreed to pay $125 million to set up a Book Rights Registry, where copyright holders can register works and receive compensation from book sales.

Google has said it wants to create an "iTunes for books" that would allow people to search for copyrighted books online and make purchases.

Under the deal Google would be able to digitize and sell so-called orphan books, those still in copyright, but with no clear owner. That has raised concern about antitrust issues.

"There are legitimate antitrust issues related to Google’s ability to solely commercialize this content," Peter Brantley of the Internet Archive told Reuters.

On Tuesday a New York judge approved a four month extension to a group of authors deciding if they want to opt out of or object to the settlement. A final settlement hearing will be on October 7.
