The International Internet Preservation Consortium (IIPC) is a worldwide consortium that joins 44 organizations from 25 countries.

The IIPC is dedicated to improving the tools, standards and best practices of web archiving while promoting international collaboration and the broad access and use of web archives for research and cultural heritage.

The Portuguese Web Archive is an innovative service based on cutting-edge technology that requires permanent investments on Research and Development activities.

Joining IIPC is a crucial milestone to establish international partnerships to enable the collaborative development of the tools used by the Portuguese Web Archive and improve the quality of the provided service.

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.

The Portuguese Web Archive will participate in the event «Presente no Futuro» (Present at the Future) – the portuguese in 2030, on the 14th and 15th of September at Centro Cultural de Belém, in Lisbon. Come and meet us.

The participants were invited, in case they were interested, to take a challenge with three steps, which included finding historical pages in the Archive.

The participants were asked to fill in a satisfaction survey, in an increasing scale of satisfaction from 1 to 7, with questions related to their experience with the Portuguese Web Archive. The obtained results show that users liked to use the service (6.1 average), that they easily learned to use it (5.9 average) and that they easily found the information they were seeking (5.1 average). It should be noted that the users claimed that they would use the service in the future (6.1) and they would talk about it to their friends (6.2).

The results obtained are positive regarding the quality of the new interface and allowed to set priorities for future service improvements.
