It's changing to a new book with same/similar authors. Current CT7 book: Economics for Business by J. Sloman, D Garratt, J Guest and E Jones (7th Ed), ISBN 978-1-292-08210-3 New CB2 book: Economics by J. Sloman, J Guest and D Garratt (10th Ed), ISBN 978-1-292-18785-3 Obviously lots of overlap - but also lots of changes, some more significant than others. ActEd will not be producing summary course notes with the same level of detail as in previous years - and so the new textbook will be required reading.
