The ‘Unlocking’ series is designed to make learning each subject area more accessible by focusing on learning needs, and by providing a range of different supporting materials and features. All topic areas are broken up into ‘bite size’ sections with a logical progression and extensive use of headings and numerous sub-headings. Each book in the series also contains a variety of charts, diagrams and key fact summaries to reinforce the information in the body of the text. Diagrams and flow charts are particularly useful because they can provide a quick and easy understanding of the key points, especially when revising for examinations. Key facts charts not only provide a quick visual guide through the subject but are useful for revision purposes also. The books have a number of common features in the layout. Important cases are separated out for easy access and have full citation in the text as well as the table of cases for ease of reference. The emphasis of the series is on depth of understanding much more than breadth. For this reason each text also includes key extracts from judgments where appropriate. Extracts from academic comment from journal articles and leading texts are also included to give some insight into the debates on complex or controversial areas. In both cases these are indented to make them clear from the body of the text. Finally, the books also include much formative ‘self-testing’, with a variety of activities including subject specific comprehension and application of the law amongst others to help the student gain a good idea of his or her progress in the course.
