SUMMA is an application designed for subscribers to the collections of DeAgostini, Hachette and EMSE publishers. It allows you to track your shipped shipments, easily pay, easily contact our customer service, and even place a reorder.

The application works in a very simple way: you need to enter your partner ID and PIN to log in.

To find your partner ID and PIN, you need to open the upper right corner of the letter you receive from us and click on the link that says "More information". Then, you will see the number and you will need to enter it in the application.
