I’m looking for a planetary system ... It doesn’t show up on the archive charts.
Are you sure you have the right coordinates? ... It looks like the system you’re searching for doesn’t exist.
... perhaps the archives are incomplete ...
If an item does not appear in our records, it does not exist!

The Historical Archives of the Department of Astronomy (AABo, Astronomical Archives Bologna) are kept at the Department of Physics and Astronomy of the University of Bologna.
They collect documents related to astronomy in Bologna since the end of 17th century, so being the most ancient collection of documents of a not private Italian astronomical institution.
The Archives are completely reorganized and inventoried and a large part of them is digitized.
The online Archives can be accessed sequentially or searched with the form.
