About the ERS books
The ERS Monograph is the quarterly book series from the European Respiratory Society. Each Monograph covers a specific area of respiratory medicine, providing in-depth reviews that give clinicians at all levels a concise, comprehensive guide to symptoms, diagnosis and treatment.
The ERS Handbooks are compact guides to broad areas of the respiratory field. Launched in 2010, the series now covers adult, paediatric and sleep respiratory medicine, includes a companion volume of self-assessment questions and features the ERS Practical Handbooks.
