A pictorial history of the famous Grey-Green bus and coach company.

Birds of Trinidad and Tobago – the definitive field guide to these bird-rich Caribbean islands – just got even better. This enhanced fixed-format version of the book – featuring songs and calls – is set to change birding, forever. Optimised for iPad, it features the book in crisp, clear high-resolution. Superb, fully zoomable colour plates of the highest detail lie opposite comprehensive identification text and accurate range maps. In addition, this e-book features songs, calls and other sounds from 179 species, placed conveniently next to the accompanying species text. The sounds included on this e-book provide a representative sample of the characteristic avian sounds on the islands. This epic collection of images and sounds represents a step change in the way birders operate. No more carrying heavy books into the field; no more trying to remember sounds days or weeks after the event, while all other methods for taking sounds into the field are consigned to the dustbin. This e-book provides a complete field-based ID solution – no birder will want to be without it.

Han Material Culture is an analysis of Han dynasty (206 BC–AD 220) Chinese archaeology based on a comparison of the forms of vessels found in positively dated tombs. The resultant chronological framework allows for the cross dating of tombs across China, of which approximately one thousand are documented here. In the context of this body of data, the development of not only vessel types but also tomb structure and decor is reevaluated, together with the pervasive intercultural exchange visible in all areas of this material. The Han dynasty emerges as a creative, surprisingly open society, heir to the Bronze Age and herald of what might be called the Age of Ceramics.

Piaget helps us to see the developmental significance of a child's failures and successes in thought and action during everyday experience by breaking down each activity into its separate mental elements. We have to tried to draw the educational implications from the developmental facts thus revealed. In recent years teachers have had to learn a great deal about mental measurement as this has become an important feature in our educational structure. This has led to much emphasis on the quantitative assessment of intellectual ability, since in most intelligence tests the main concern is with the number of right responses. In his 'open-ended tests' Piaget seeks to find in a large number of situations what it is that we take for granted which the children have not grasped. To do this he examines the processes of thought and the degree of success and failure, which should be of much greater diagnostic value to the practising teacher. It also gives further support to those who believe in the need for an individual approach to each child's learning. For many years, people who have worked in child centred education have had philosophical theory and intuitive judgment to guide them, but have lacked scientific justification for what they were doing. Piaget's work is now providing scientific evidence from experiments, with concrete examples and demonstration from children's behaviour for what was previously a matter of opinion. We have chosen the examples to cover a wide age range partly to emphasise the genetic approach and partly to appeal to as wide an audience of teachers as possible. In addition we tried to choose pieces that held special promise of applicability in schools.
