This second edition of the Encyclopedia of Nursing Research (ENR), like the first, is a
comprehensive, yet concise and authoritative guide to existing nursing research literature. It
charts the course of nursing research since 1983 when the first edition of the Annual Review
of Nursing Research (ARNR) was published.
The original edition of ENR, published in 1998, grew from a long-standing commitment
of the publisher, Dr. Ursula Springer, to the field of nursing, and my commitment to nurse
scholars around the globe. The original encyclopedia followed 15 years of publication of the
ARNR series. This second edition of ENR follows publication of 22 volumes of ARNR and
incorporates the research topics included in the ARNR series. Through these formative years
of nursing science, I have had the privilege of serving as editor of the ARNR series and
witnessing the rapid growth of knowledge and expertise in nursing research. Having served
as editor for the first edition of ENR, I am joined in this edition by Meredith Wallace, the
Associate Editor.
