Another on-line source is The Digital Library of Slovenia.

It includes many collections, which are scanned and fully searchable.

The search page is: http://www.dlib.si/dlib_eng.asp
For more results - mark the full-text search circle.

The collection includes old journals like the "Amtsblatt zur Laibacher Zeitung
in which there are news >from all over the Austro-Hungarian empire.

The site is very slow and sometimes requires several trials in order to search
or downlowd a pdf file.
