The most important event in the history of the collection was the digitalisation of the items and their publication on the website in July 2012. The www.kulturazrzuty.pl website was created with the support of the City of Culture Foundation (Fundacja Miasto Kultury), founded by Zofia Łuczko and her husband a few months earlier. Most of the materials available on the website come from private archives of the Łódź Kaliska members and other participants of these events: Grzegorz Zygier and Zofia Łuczko.

The push to collect and digitise the archival materials came as a result of two meetings in April and June 2012 dedicated to the history and the achievements of the Pitch-In Culture. Pitch-In Culture was active between 1981 and 1987, while vast majority of works and pieces of documentation from that period, which now are part of the collection — such as the 1983-1985 artistic Tango magazine — came into existence during activities at The Attic (1981-1985) and plein-air sessions in Teofilów (organised in 1983, 1985, 1987, and 1990).
