i love the spirit of squatters youtube channel, it has loads of good stuff-

and yeah following on from above posters, the benefits of archiving in some sort of institution are clear - people have access to it, there's less chance of it being stolen/destroyed
besides, on a 2 minute check of the iisg website, it seems you can search their catalogue:
The catalogue, indexes on archives and image and sound collections, some databases, and the IISH-website can be accessed through search.iisg.nl.
For information on consultation of documents, ordering reproductions, address and opening hours of the reading room - go to Services.
in any case, don't throw it away!! i heard that's what eric duinvoorden ended up doing with a lot of stuff....
