How do I reference the Royal Marsden Manual in APA (7th style)?
Answer
Because this book has individual authors for each chapter you should follow the example for a chapter in an edited book https://libguides.swansea.ac.uk/APA7Referencing/BooksEditedChapter
For each chapter you use, you will need a separate reference.
Here is an example:
In text:
Grayer et al. (2020) argues that...
OR
.....(Grayer et al., 2020).
In the reference list
Grayer, J., Baxter, J., Blackburn, L., Cooper, J., Curtis, E., Dvorjez, L., Finn, L., Gaynor, D., Henderson, B., Jagger, C., Keating, L., Leigh-Doyle, J., Lister, S., Mathiah, R., & Mohanmmed, A. (2020). Communication, psychological wellbeing and safeguarding. In S. E. Lister, J. Hofland & H. Grafton (Eds.), The Royal Marsden manual of clinical nursing procedures (10th professional ed., pp. 124-193). Wiley-Blackwell.
