I want to start highlighting new Islandora sites as we come across them, so please let me know when you find or create a new site using the Islandora framework.
The BESS (Biblioteca Elettronica Di Scienze) Digital Archive is a new Islandora site in Italy:
Archivio digitale di BessBiblioteca digitale sulle trasformazioni sociali ed economiche del Piemonte e Torino | Digital library on the social and economic transformations of the Piedmont and Turin
The BESS team has also done a great job of documenting their effort on a Dev Page, including a comprehensive PDF guide to their processes. Excellent work and a good indication of what can be done using open source software!
