@Hack-Hook when I was in University (in one of not big Cities of Iran) I and my friends usually went to library in the city and I can assure you that library were full of the young girl and boys.
Sometimes we couldn't find empty table and seat, so we need to go to another library or university library.
when I look new generations (my cousins), I can see they are continuing to go to libraries. At least libraries are good places to young boys and girls see each other in healthy environment.
I said this to say Iranian are continuing to read books hopefully but I am agree that is not enough good yet.
@KediKesenFare
Iran have one of the biggest book gardens of the world. and as you can see that place is most of the time busy.
