Unfortunately, the library does not have a dedicated Rheumatology specialty section. Here's a summary of what's available:
The library covers these specialties: Anatomy, Anesthesiology, Biochemistry, Cardiology, Community Medicine, Dermatology, Embryology, Emergency Medicine, ENT, Family Medicine, Gastroenterology, General Surgery, Genetics, Histology, Immunology, Internal Medicine, Laboratory Medicine, Microbiology, Nephrology, Neurology, Neuroscience, Obstetrics & Gynecology, Ophthalmology, Orthopedics, Pathology, Pediatrics, Pharmacology, Physiology, Psychiatry, Pulmonology, Radiology, and Urology.
No Rheumatology-specific books are in the library. However, rheumatological topics (e.g., rheumatoid arthritis, lupus, gout, vasculitis, connective tissue diseases) are likely covered within the Internal Medicine (5 books) and Orthopedics (3 books) sections. If you'd like, I can search those for specific rheumatology topics.
