David M. Guion, the All-Purpose Guru, is a librarian and multi-specialist. He has education, training, and experience in several subjects and publishes the fruit of careful research in order to proved reliable and accurate information.
His two books on the history of the trombone place him among the world's foremost authorities on the subject--a very large fish in a very small pond. As a blogger and an author for the Amazon Kindle platform, he aims to be a reasonable sized fish in some roomier ponds: classical music, American popular music (before rock), sustainability and green living, research and writing, food, and the Bible.
David seeks to connect with readers who have an interest in his topics, but not necessarily specialists' knowledge. Besides his Kindle books, he writes four blogs (Musicology for Everyone, Grace and Judgment; Reading, Writing, Research, and Sustaining Our World) and has posted numerous articles to Hub Pages.
Librarians specialize in organizing the world's knowledge and looking it up.
David knows how to conduct thorough research and communicate his findings to interested non-specialists in language that's clear, easy to understand, interesting, and sometimes funny.
