It explores how the texts from classical Greece and Rome have survived and gives an account of the reasons why it was thought worthwhile to preserve them for future generations. In this 4th edition adjustments have been made to the text and the notes have been revised in order to take account of advances in scholarship over the last twenty years. 'The third edition of this superb work has been carefully revised to reflect advances in classical scholarship since publication of the previous edition. The work is indispensable for classical students who have not read the previous edition, and recommended for those who want recent information on an essential subject.'
