We particularly need your help, to identify relevant Portuguese sites hosted outside the country domain .PT (e.g. .COM, .NET, .EU).

The information published on the web is a resource of great historical value that must be preserved for future generations.
RARC is an application that enables anyone to contribute to preserve the web, by providing a little bit of disk space to store a backup copy of the archived information.
This way, if information is lost from the central repository due to, for instance, a natural disaster, it can be retrieved from the computers of the people that installed rARC.
RARC includes a screen saver that presents examples of archived pages. You can uninstall rARC or reduce the donated space whenever you want.
Comments and suggestions are most welcome.
The Portuguese Web Archive publishes a top of the most generous contributors and the approximate location of the backup copies.
Start contributing to rARC now!
Thank you for your support.

The paper Trends in Web Characteristics, by João Miranda and Daniel Gomes, will be presented at the 7th Latin American Web Congress (LA-Web), in Merida, Mexico.
This paper presents trends in the evolution of the Web derived from the analysis of 3 characterizations performed within an interval of 5 years. The Web portion used as a case study was the Portuguese Web. Several metrics regarding site and content characteristics were analyzed.
Congratulations and thank you for this important contribution to Web Archiving!

Several organizations around the world are struggling to archive information from the web before it vanishes. However, users demand efficient and effective search mechanisms to access the already vast collections of historical information held by web archives. The Portuguese Web Archive is the largest full-text searchable web archive publicly available. It supports search over 1.2 billion files archived from the web since 1996.
The paper Creating a Billion-Scale Searchable Web Archive was presented on the Temporal Web Analytics Workshop 2013, in Rio de Janeiro, Brazil.
