Book excerpt: This major project comprises fourteen thematically arranged volumes. The aim of the Compendium is to examine the interlocking strands of history and traditional culture that go into the making of a national identity, in an up-to-date synthesis of the current state of knowledge. By bringing together information from a variety of sources, the Compendium not only provides a digest of topics, but also points towards areas for new investigation. The Compendium concentrates upon the present and the historical period and does not generally deal with prehistory, although for certain themes, such as the development of agriculture and buildings, early evidence is taken into account. Where appropriate, reference is made to foreign parallels and to the influence on Scotland of the cultures of neighbouring peoples. Scottish influence on the world at large is also taken into account, whether in relation to urban or rural, maritime or land-based topics. Material and non-material aspects of history and tradition are considered equally, at all levels of society, indeed oftentimes focusing on the interaction between people of differing social strata
