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 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.
