Below are sentences:
Aquí se venden muchos libros.
Would saying it in classical passive (done by) change its meaning?
Muchos libros son vendidos aquí.
Am I correct to conclude that there are the following differences between two:
- former is more widespread
- with former you cannot precise by whom books are sold
- latter is rarely used, more informal
- with latter you can omit by whom books are sold (like in former sentence), but with this construction you can mention by whom it is sold (if you want to)
Just in case, I know how "Se" is used in impersonal rather than reflexive way, so to avoid ambiguity I deliberately used example in plural form.
