About Logical Expressions

Susan Daffron is the President of Logical Expressions, Inc. a book and software company that is based in Sandpoint, Idaho. She owns and operates the company with her husband James H. Byrd.

Since 1995, Logical Expressions has been providing writing-related services for companies in the high-tech computing industries. The company also publishes books on a variety of topics.

Susan has published her own books, a book series (publishing other authors), books through traditional publishing houses, and worked for a publishing company before starting Logical Expressions, so she often consults with authors who want to learn more about book publishing. Because of her background in graphic design, Web design, editing, and publishing, she has been exposed to most facets of the book publishing business.

Logical Expressions also devised, developed, sponsored and hosted the first virtual event for self publishers, the Self-Publishers Online Conference (SPOC) and offers author and publisher training at SelfPubU.
