From the BBC:
Historic Scotland has launched an online database cataloguing 400 objects from dozens of historic sites in Scotland.
Artefacts, paintings and items spanning 2,000 years are available to view at the touch of a button.
The searchable online gallery includes the story of each item on display.

A bit more from Historic Scotland:
More than 35,000 objects housed in over 160 properties in Scotland are in the safekeeping of Historic Scotland. This is the first time many of the objects can be viewed outside of their host properties. So the hidden gems contained in Innerpeffray Chapel near Auchterarder, Arbroath Abbey or Edinburgh Castle can be viewed from a computer or smart phone in Stornoway, Motherwell or Castle Douglas. The gallery is also an opportunity to view items from the Historic Scotland archive that are not currently on public display.
An advanced search interface is also available.
