The texts of the editions here are all different; however they do all clearly belong to the same translation. As best as can be determined, the original translation was posted to winguts.com; a Spanish Harry Potter fan site and the the earliest example appears to be attributed to "winguts". A major revision occurred at some point giving us four exemplars that are clearly related. The two electronic versions had metadata creation dates that allow us to date them to 2011 and 2016; 2011 had no attribution and 2016 included a reference to the website spanishhallows.blogspot.com which this translation was originally (mistakenly) attributed to. The two print editions have no attribution and no dates, so it is impossible concretely provide a timeline (which is why they currently are not broken into separate variants). Perhaps a close examination of the texts would allow us to determine the relationship; for the time being only a cursory comparison was possible. It is entirely possible—perhaps likely—that all four versions were produced independently by completely different individuals.
