Note: The series was launched in 1965, devoted to publishing national and international fiction in low-cost, paperback editions. In the seventies, the series started differentiating in sub series; one of them 'Oscar Fantascienza', continued with the normal Oscar numeration, adding 'Fantascienza' and a new progressive number on the spine along with the usual Oscar series one and a logo usually presented on the top of cover page stating 'Oscar Fantascienza Mondadori' (number 1 issued for "Buone notizie dal Vaticano", Oscar #917). From Oscar #1876 (Oscar Fantascienza #52) the logo changed, with 'FANTASCIENZA' in a silver band, with a smaller 'Oscar Mondadori' always on the top of cover page, keeping the double numeration that will last to the number Oscar #2138 - Oscar Fantascienza #78. source Oscar Mondadori in italian
