Let's move left to right...
I have The Well Designed Mixed Garden by Tracy DiSabato-Aust and Planting the Natural Garden by Piet Oudolf...because we all have to have hobbies and my previous profession is landscape.
Barron's Spanish-English Dictionary and the Borm Bruckmeier Medical Spanish Pocket Dictionary...because I am always encountering nursing and medical terms that I don't already know in Spanish. I also have NTC's Dictionary of Mexican Cultural Code Words because it's a really neat reference and great way to explain culture and language to people unfamiliar with Mexican culture.
I have Walt Whitman's Leaves of Grass and Twelve Steps to a Compassionate Life by Karen Armstrong.
Now for the nursing-related material:
I have a several of Mary Ann Hogan's Reviews and Rationales and the Saunders Comprehensive NCLEX Review...because I do a lot of practice questions and these are the best review texts that I have laid hands on. There's also Nugent's Fundamentals Success, which is a great questions book for fundamentals.
Now a list...
Anne Abrams, Clinical Drug Therapy, Rationales for Nursing Practice which I got in a free pile of book, but I would have paid for if I had known how good it was.
Taber's and the Strunk & White's Elements of Style also.
Netter's Atlas of Human Anatomy, which is beautiful and I recommend highly!
Marilynn Doenges, Nurse's Pocket Guide, which I rate a solid "meh" and I am constantly in search of a better care plan book.
Sharon Jensen, Pocket Guide for Nursing Assessment, which I rarely use but don't outright despise.
Potter & Perry, Fundamentals of Nursing which was alright, but I really love the Clinical Companion that accompanied the text. It's small and portable and has lots of useful, basic info.
Joyce LeFever Kee, Pharmacology which is a wonderful text.
Mosby's Nursing Drug Reference and Betty Gahart's IV Meds book which are both solid drug books.
Shannon Perry, Maternal Child Nursing Care which is too darn verbose and in need of a serious edit for unnecessary wordage.
Mary Townsend, Essentials of Psychiatric Mental Health Nursing which is great text.
Mosby's Manual of Laboratory and Diagnostic Tests, which makes a fine door stop, but which I hate using.
and Lewis Med-Surg, which has I think is fantastic.
Now the list of books I would have on my desk is much larger, but I'm so broke!
