  The present work falls in the line of activities promoted by the European
Languguage Resource Association (ELRA) Production Committee (PCom) and raises
issues in methods, procedures and tools for the reusability, creation, and
management of Language Resources. A two-fold purpose lies behind this
experiment. The first aim is to investigate the feasibility, define methods and
procedures for combining two Italian lexical resources that have incompatible
formats and complementary information into a Unified Lexicon (UL). The adopted
strategy and the procedures appointed are described together with the driving
criterion of the merging task, where a balance between human and computational
efforts is pursued. The coverage of the UL has been maximized, by making use of
simple and fast matching procedures. The second aim is to exploit this newly
obtained resource for implementing the phonological and morphological layers of
the CLIPS lexical database. Implementing these new layers and linking them with
the already exisitng syntactic and semantic layers is not a trivial task. The
constraints imposed by the model, the impact at the architectural level and the
solution adopted in order to make the whole database `speak' efficiently are
presented. Advantages vs. disadvantages are discussed.
