[Preface] The Authors - e-Reading Library

The Authors

This book had three main authors: Jerry Peek, Tim O'Reilly, and Mike Loukides. But we had material from a host of contributors-either people who originally posted a good tip to Usenet, authors of Nutshell Handbooks who let us take material from their books, or authors of software packages who let us take a few paragraphs from README files or other documentation.

Here's a list of authors, their initials, and the articles that they wrote or contributed to:
