Thanks for your kind words. Much appreciated!

Note that you could use the Memento extension to consult your archive on the premises of the library if:

Your archive supports the Memento protocol. The most recent Wayback software version is 100% compliant with the most recent version of the Memento protocol.

The TimeGate of your archive is added to the list of TimeGates in the Memento extension for Chrome. The possibility to do this in the Options area of the Memento extension is currently being implemented.

Cheers

Herbert

Now right-click on a web page, and click the "Get near …" option from the Memento sub-menu to see what the page looked like around the selected date. Do the same for any link in a page to see what the linked page looked like. If you hit one of those nasty "Page not Found" errors, right-click and select the "Get near current time"

It also allows time travel in all language versions of Wikipedia. There's two things Memento for Chrome can not do for you: obtain a prior version of a page when none have been archived and time travel into the future. Our sincere apologies for that.

> Technically, the Memento for Chrome extension is a client-side implementation of the Memento protocol that extends HTTP with content negotiation in the date time dimension. Many web archives have implemented server-side support for the Memento protocol, and, in essence, every content management system that supports time-based versioning can implement it. Technical details are in the Memento Internet Draft at http://www.mementoweb.org/guide/rfc/ID/. General information about the protocol, including a quick introduction, is available at http://mementoweb.org.
