Philip Smith is a relatively common name, and there might be several authors and editors by that name, each with distinct careers and areas of expertise. Without more specific information, it is difficult to provide an accurate description of the particular Philip Smith you're asking about. If you are referring to an editor in the literary world, Philip Smith might be known for his work on anthologies, academic journals, or for a publishing house, where he would manage the process of reviewing, revising, and preparing manuscripts for publication. If you are referring to a specific Philip Smith who has a notable body of work, like the Philip Smith who edited the book "New York in the 70s" as a photographic essay or Philip Smith known for other works, providing more context or detail would enable a more accurate and detailed description of his contributions as an author and editor. Please provide additional information so that I can offer a more targeted description.
