 The Siena Music Academy library in Siena is specialised in music and musicology. It is functional to the students attending our masterclasses, but also to researchers, scholars and music teachers of all levels. Using Alma means to share information about music scores and parts that would be otherwise kept in our palace and offer them to a broad range of users. Alma provides an easy way of contributing to the Italian National Library Service collective catalogue. This has opened our library to a wider national dimension ready to reach a larger number of musicians and musicologists. Besides, Alma is periodically implemented with new functions and templates, which allow the cataloger to treat an increasing number of items In a musical founder, we may have printed music, modern or ancient books, periodicals and even objects. Alma gives the possibility to list a variety of materials that had to be treated separately before using different softwares. Move to Alma was a good opportunity to consolidate the collaboration between the three university, Florence, Pisa and Siena, collaboration born in the past with SFX and Metalip and more recently with the adoption of Primo and bring it to a higher and more complex level with the definition of the network zone and the adoption of common cataloging moves. Thanks to Alma and its network zone, we contributed to the National Project SBN National Library Service maintaining a wide level of autonomy guaranteed by the flexibility of the new SBN architecture and the possibility to operate in its own working environment taking into account the local choices and the needs of different realities that contributed to SBN. The new architecture has allowed to share the cataloging at the network level with the creation of a single new SBN university traditional app, which has incorporated the historical work done by the Florentine Bar in the context of the National Cooperation and sanctioned the entry of the bar of Pisa and Siena in SBN. The adoption of this organizational model has led to the shift at the network level of many activities carried out so far at the local level. With the network zone, we have the ability to manage and maintain the authority file of orders and subject in addition to the verbal translation of the notifications. This simplified the procedures and the times of cataloging in an important element in a period of strong construction of the resources. Contributing to the National Catalogue is a great opportunity to give greater visibility to the collection of the libraries of the University of Siena and all the libraries that are part of the Sienese Library Service.
