Many of us use the internet to search for information [] We often mention Wikipediahellip
Everything is of course on Wikipedia Just type in a name and you can read entire essays (man 70s)

Many of us use the internet to search for information [] We often mention Wikipediahellip
Everything is of course on Wikipedia Just type in a name and you can read entire essays (man 70s)

When we have to find information about WW2 outside the class setting we fully concentrate on digital resources like Google and Wikipedia (school kids)

Everything is of course on Wikipedia Just type in a name and you can read entire essays (man 70s)

Many of us use the internet to search for information [] We often mention Wikipediahellip
Everything is of course on Wikipedia Just type in a name and you can read entire essays (man 70s)
Over half of us think that Wikipedia and Google contribute to our knowledge and understanding of history
When we have to find information about WW2 outside the class setting we fully concentrate on digital resources like Google and Wikipedia (school kids)

Everything is of course on Wikipedia Just type in a name and you can read entire essays (man 70s)

Report on interest in WW2 among Dutch population
httpwwwoorlogsbronnennlgebruikersonderzoek2015 May 2015
Many of us use the internet to search for information [] We often mention Wikipediahellip
Everything is of course on Wikipedia Just type in a name and you can read entire essays (man 70s)
Over half of us think that Wikipedia and Google contribute to our knowledge and understanding of history
When we have to find information about WW2 outside the class setting we fully concentrate on digital resources like Google and Wikipedia (school kids)

Unstructured data (PDF flat file)

To summarize
a lot of information is available about these WW2 underground newspapers
