University College Dublin's (UCD) Digital Library has much to offer its visitors, with content that appeals to researchers as well as general viewers. Its myriad collections include gems such as the Beranger Watercolors, which are a lovely set of "18th century watercolours of Irish antiquities, done by or for Gabriel Beranger;" a collection of eighteenth and nineteenth century historic maps of Dublin and Ireland; and photographs of religious artifacts, such as chalices in the collection Material Culture of the Mendicant Orders in Ireland. To make these and other collections available online, the UCD Digital Library works closely with many other repositories of archival materials, including the UCD Irish Dialect Archive, the UCD School of Art History & Cultural Policy, and the Urban Modelling Group. Collections and items in the UCD Digital Library are accompanied by detailed descriptions and extensive metadata, and many document images can also be downloaded as PDFs.
