Unlike the Websites of some national archives, the National Archives of Scotland site does not post their collections online. The site does offer, however, a complete catalog of the collections, which includes private and government materials providing "sources of the history of Scotland as a separate kingdom, her role in the British isles and the links between Scotland and many other countries over the centuries. The NAS holds records spanning the 12th to the 21st centuries, touching on virtually every aspect of Scottish life." Researchers and visitors may browse the catalog entries for the pre- and post-1707 collections according to their type, which include but are not limited to government records, court records, papers of the Scottish parliament, public registers, private papers, church records, maps and plans, and industrial records. Downloadable .pdf format fact sheets offer information and advice on using the collections to research a variety of popular topics, such as adoption and emigration. There is also an education section with fact sheets for teachers designing lesson plans. Finally, the Website offers an online bookshop and describes a number of services to researchers, including instructions on ordering some documents.
