You can consider getting these books useful for your respiratory training:

• Oxford Handbook of Respiratory Medicine: handy to have around the office and dip into on your commutes. Does get out of date so try to get the most up to date edition, but a broad concise covering of all major topics and the only handbag-sized comprehensive text.
• Ernt’s Introduction to Bronchoscopy: good for increasing confidence when you have limited experience. Worth reading on your way in on days when you’re doing Bronch to remind yourself particularly of the anatomy.
• Ellis’ Interpreting Chest X-rays: Steve Ellis, of Barts Hospital fame (and familiar to anyone who has been to the MDT there) provides a comprehensive but accessible look at chest x-ray interpretation. Spot on for Resp SpRs.
• The Chest X-ray – a survival guide: the book you get free on the Northwick Park Radiology course. Accessible, with many example films
