The demonstration session of the Portuguese Web Archive aimed to bring participants to experience, in an informal and relaxed way, the Archive and its features in order to identify faults and points to correct, and record users’ suggestions to improve the system.

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.
