The aim of this book is to help teachers and students in Ancient Philosophy to find their way into the vast amount of modern publications about Plotinus. It collects over 50 years of research in a single and easy-to-use book, containing over 1500 entries in all languages. The first part of the book deals with modern translations of Plotinus’ treatises, while the second part lists studies concerning particular aspects of Plotinus’ thought. The work ends with a series of four indexes allowing the reader to find any references quickly. This bibliography contains all the entries that have been listed in the different existing bibliographical indexes. These entries have been corrected and completed with small summaries when necessary.
