This index joins two companion volumes of books and chapters devoted exclusively or primarily to the topic of self-directed learning. The book contains 141 abstracts of books, chapters, published articles and papers, and unpublished ERIC documents. Chapter 1 is an introduction. Chapter 2 provides an analysis of the 141 abstracts reported in chapter 4. It is presented in five sections: abstract topics, quantity of publications by topic, research method and design, instruments, and authors. Some conclusions based on the analysis are shared. Chapter 3 describes the five indexes and provides definitions of some key terms. Chapter 4 contains the abstracts. Each abstract is organized into one of two formats. All have the following elements in common: author's name; title; source of the work; year the work was published or filed with ERIC; subject(s) covered; type of research or style of presentation; and purpose of the work. Items that report research involving instruments and populations have the following format: sample size and characteristics, instruments used, and conclusions. Items based upon work that did not involve the use of instruments or populations list points made or covered in the text and conclusions. Five indexes are provided: author, subject, type of work, instrument, and year of publication. Indexes direct the user to abstracts by referring to a serial number assigned by the authors rather than to a page number. (YLB)
