Lattice Theory: Foundation

This book started with Lattice Theory, First Concepts, in 1971. Then came General Lattice Theory, First Edition, in 1978, and the Second Edition twenty years later. Since the publication of the first edition in 1978, General Lattice Theory has become the authoritative introduction to lattice theory for graduate students and the standard reference for researchers. The First Edition set out to introduce and survey lattice theory. Some 12,000 papers have been published in the field since then; so Lattice Theory: Foundation focuses on introducing the field, laying the foundation for special topics and applications.

First Meetings

Orson Scott Card - First Meetings

In July 1977, "Ender's Game" appeared as a novelette in Analog magagzine. The science fiction community immediately embraced it, nominating it for a Hugo Award, and when Orson Scott Card turned it into a novel in 1985, it won both the Hugo and Nebula Award. Now, twenty-five years later, First Meetings celebrates "Ender's Game" by re-releasing that original story with three others, two of them never before available on audio and an original dramatization never published anywhere.

The Modern World, Volume 4: Civilizations of the Middle East and Southwest AsiaThe history of the modern Middle East and Southwest Asia goes back thousands of years. Indeed, the region was a center of civilization in prehistory and one of the areas in which agriculture originated and the world’s first cities were built. Yet the region faces a host of contentious issues—political, social, religious, and economic.

This region has been a center of human settlement for thousands of years. It was the site of the earliest urban centers, the invention and first use of the wheel, and the development of the first alphabet, number systems, lunar and solar calendars, and many more innovations.
