In this paper the problem of multiple releases from a single survey is addressed. The design and release of a public use file derived from a microdata file for research are discussed. Problems and benefits of multiple microdata releases are tackled. In order to satisfy wider variety of user needs, the aim of this work is to extend the microdata portfolio of a National Statistical Institute, without additional resources. Results obtained when applying the proposed methodology on the Italian Small and Medium Enterprises survey are illustrated.
