In <i>Six Years</i> Lucy R. Lippard documents the chaotic network of ideas that has been labeled conceptual art. The book is arranged as an annotated chronology into which is woven a rich collection of original documents--including texts by and taped discussions among and with the artists involved and by Lippard, who has also provided a new preface for this edition. The result is a book with the character of a lively contemporary forum that offers an invaluable record of the thinking of the artists--a historical survey and essential reference book for the period.
