Elsevier is one of the largest publishers of scientific journals and books. If a person has heard of Gray's Anatomy (the book, not the television show), that person knows what is probably the most famous title published by the company. While it's true that most people know this title, Elsevier's publications are primarily geared toward medical students and professionals. Their publications cover almost every area of medical health. At Elsevier, a book buyer will find reference materials for veterinary medicine, books about every field of human medicine from A-U (apparently there are no medical departments that start with the last few letters of the alphabet), educational materials about dentistry and so much more. And the company is determined to supply its customers with the information they need in the format they want. That's why many titles are available in a variety of formats including print, online and as e-books.
