2005 contents provided by the National Library can now be searched

The contents provided by the National Library of Portugal were successfully integrated and can be searched through our experimental search system.

In 2005 the National Library of Portugal in collaboration with INESC conducted a series of web crawls to gather information related to the national elections.

This project was named RECOLHA and the data collected comprised over 14 million contents (165 GB).

In 2009 these data was supplied to the Portuguese Web Archive.

It was successfully integrated and now it can be searched through our experimental search system.

Notice, that searches are performed over all the archived data, independently from their origin, so you will not be able to identify the RECOLHA contents.
