Your questions will entice our 7,500 linear metres of archive and library documents to reveal their stories about the past. The archive database allows you to research our holdings. They are not arranged by subject, but by origin, i.e. by the regions of the PTT and the departments of its central administration. Our scientific specialist library contains current and historical publications dedicated to the subject of communication. If you have any questions or information about our holdings, we will be happy to assist you. You can find our contact details here.

The holdings of the PTT archive are arranged according to their origin, i.e. according to the regional division of the PTT and the departments of the central administration and not according to topics. In our special scientific library you will find current and historical publications on mail, telephony, telegraphy and telecommunications. If you have any questions about our holdings, we will be happy to assist you. You can find our contact details here.

Digital contents

Other retro-digitised documents stored on external platforms are the result of our cooperation with other cultural institutions:

We are currently retro-digitising our phone directories. The first ones are available online in our Digital Reading Room (click here to go directly to the inventory). We will be constantly releasing more online.
