I should also mention that some authors or publishers allow free downloads for educational purposes. The user might not be aware that downloading copyrighted material without permission is illegal and unethical. So it's important to emphasize that. Then, if the user can't find it legally, alternatives like public libraries or interlibrary loan services might help. Maybe suggest looking for the original Latin text if the Spanish translation isn't available for free. Also, maybe recommend purchasing a digital version if the user can't access it through legal means.
