In the internet there are several projects with this focus.
For some time, there has been the website Stuttgart-Album.
There you will find photos of Mineralbad Berg, a swimming bath 50 years ago, when swimcaps were mandatory or of the solar eclipse 1999.
There will also be a real book of the project in October.
The newspaper Stuttgarter Zeitung shows pictures from once upon a time now and then, for example
the former "amusement center", made out of wood cabins, the so called "united cabins or Vereinigte Hüttenwerke" which had been on the ground of the now existing Schwabenzentrum.
Even Castle Square has been different a picture from the seventies shows a nearly void square which will be difficult to find nowadays.
In 2016 the new city museum - Stadtmuseum Stuttgart in the Wihelmspalais will be opened.
The Wilhelmspalais was home to the library - Stadtbibliothek before and has now moved to another place. Of course objects to be presented are collected already and some theme exhibitions have already be organized.
