But I have to be careful not to fabricate information if the user is under the impression it's real.
I should also consider the possibility of a misspelling. For example, "Caballero" might be part of a longer title, or the PDF is part of a larger work. Maybe the user saw a reference online but got the title wrong. In that case, providing guidance on how to search for similar publications would be helpful. caballero rivista pdf
