The ALADIN Catalog is a listing of all the books, journals, videos, and other materials that are available at Gelman and the consortium libraries. The ALADIN Research Portal is the gateway to the more than 200 databases the library subscribes to for access to magazine, newspaper, and journal articles; dissertations, proceedings, archives and other research materials.
