HTTP Framework for Time-Based Access to Resource States - Memento
The HTTP-based Memento framework bridges the present and past Web by introducing datetime negotiation and TimeMaps, a variation on content negotiation that leverages the given resource's URI and a user agent's preferred datetime.

It is argued that the use of complex object formats as OAI-PMH metadata formats results in a reliable and attractive approach for incremental harvesting of resources using the OAI -PMH.

Although reverse engineering remains heavily dependent on the human component, a number of automated tools are presented that aid the reverse engineer.
Losing My Revolution: How Many Resources Shared on Social Media Have Been Lost?
This paper explores how many resources shared in social media are still available on the live web or in public web archives and concludes that after the first year of publishing, nearly 11% of shared resources will be lost and after that the authors will continue to lose 0.02% per day.

A resource versioning mechanism that is fully based on HTTP and uses datetime as a global version indicator and allows "follow your nose" style navigation both from the current time-generic resource to associated time-specific version resources as well as among version resources.

The Memento Project's archive access additions to HTTP have enabled development of new web archive access user interfaces, and approximating the Web via sampling URIs from DMOZ, Delicious, Bitly, and search engine indexes and measuring number of archive copies available in various public web archives indicates that 35%-90% of URIs have at least one archived copy.
Not all mementos are created equal: measuring the impact of missing resources

It is shown that Web users’ perceptions of damage are not accurately estimated by the proportion of missing embedded resources, and a damage rating algorithm is proposed that provides closer alignment to Web user perception.
