Since 1995, Magill\'s Medical Guide has had a reputation for providing general readers with the most authoritative yet accessible reference source that helps bridge the gap between medical encyclopedias and dictionaries for professionals and popular self help guides. The Guide is a staple in high school, college, public and medical school libraries. A perfect mix of accessibility and depth, Magill\'s Medical Guide provides general readers with an authoritative reference. Now in its sixth edition, Magill\'s Medical Guide expands to six volumes and contains 1,178 entries. 161 essay topics are completely new to this edition, and all entries from the previous edition have been evaluated and updated by a panel of Medical Editors to ensure their currency and accuracy, as needed. All cross references to other relevant entries in Magill\'s Medical Guide have been revised. Every bibliography has been updated with the latest editions and sources, including Web sites for relevant organizations. All appendixes from the previous edition have been updated and checked for accuracy, and the "Medical Journals" list has been expanded to include standard title abbreviations.
