It does not seem to get a lot of media attention in the US, but yesterday in Cologne the building of the Archive of the City collapsed. Some assume it has to do with underground building works. The collection in this city archive contains original records since the 10th century, the records of the Chancellery of the Hanse from the beginning till the 17th century, all files regarding Cologne's role as leader of the Rhenish Free Cities within the Holy Roman Empire from 1478 till 1795, all archives and record of the monasteries in Cologne since the 11th century till 1795 (approx. 19'000 documents), privileges issued by Otto The Great and others, the complete literal estate of Heinrich Boell, the more than 340 volumes of the protocols of the City Council since the 1288 till 1795, parts of the records of Imperial Chamber Court from 1495 till 1803, certified original copies and originals of the imperial recesses from 1288 till 1795, and much more.
If the collection would be lost, it would be a national catastrophe for Germany. The worst cultural lost in times of peace.

Are the contents of the missing or imperiled documents copied elsewhere? While it is nice to have the original, having the information is the essential thing.
