About John Gale

I work as a medical librarian in the Joint Education and Training (JET) library at Leighton Hospital, Crewe. I keep clinicians up to date with the latest research, help them to find the best information about treatment and train them to find - and assess - high-quality information for themselves. I also help doctors and nurses find and write high-quality information for patients.
