The standard commercial edition is a printed paperback (rústica). There is also a hardcover (tapa dura) edition used for libraries/institutions, but the common student/resident version is paperback.

Here is the correct information:

2018 (this is the Spanish translation of the English 11th edition from 2014)

The English 12th edition (2024) exists, but as of now, McGraw-Hill has not yet published an official Spanish 12th edition . Therefore, the Spanish 11th edition remains the latest available Spanish version. If you need the most up-to-date content in Spanish, you may need to check if a 12th edition translation is forthcoming.

I understand you're looking for the , and you want to know the proper paper format (likely meaning the official printed edition, or a legitimate paper version as opposed to a digital copy).
