The last two volumes of Jung's Collected works have now been published. They ought to provoke a spate of research.

The General bibliography records the initial publication of each original work by Jung, each translation and significant revisions and expansions. It is quite awe-inspiring to think that Jung's works exist not only in German, English, French and Italian, but in a host of other languages, some as unusual and limited in terms of the people who speak it, as Serbo-Croatian, Slovene, Turkish, Hungarian or Hebrew. All are listed here, and all the translations are related by cross-references to the work from which the translation was made.

The Bibliography also records all Jung's forewords, letters, book reviews, newspaper articles, published texts of lectures and volumes of seminar notes, all organised chronologically.

The editors have sought to provide not only as nearly complete a record as possible of Jung's publications, but they also hoped to help throw light on the sequence of development of his ideas. This volume should, therefore, prove particularly useful to all those concerned to study the history of Jung and the history of his researches, thoughts, interests, preoccupations and theories.

The General index to the Collected works is absolutely invaluable for those who want to explore in depth Jung's concepts, the use he made of them, the way they changed, developed, became modified and interrelated, and the exact meaning or meanings and attributes he ascribed to them. It will undoubtedly be most useful and almost essential to the attempt, now in process, to produce a dictionary of Jungian terms. It will also serve those who want to examine the precise connection between Freudian and Jungian terms and Freudian and Jungian concepts, and the possible cross-fertilisation that has undoubtedly taken place whether known and acknowledged or not.

This General index, though based on the contents of the separate volume indexes to the Collected works is, in fact, mor
