The Universes of E. E. Smith

This book is a comprehensive concordance with entries for characters, places, events, and many other topics in the "Lensman" and "Skylark" novels of Edward E. "Doc" Smith.

The entries range from only a few words for such minor subjects as "X-plosive" to almost six pages for "Kinnison, Kimball."

It is intended for those with nostalgic affection for the early "space opera" days of SF.

The book, written by SF fans Ron Ellik and Bill Evans, includes a bibliography by Al Lewis and black-and-white illustrations by Bjo Trimble.

It was published by Advent in 1966.
