@Surya @brahmajijnasa @TheDestroyer I just found a chapter of the Padma Purana which gives a list of 21 Puranas which is a mixture of Mahapuranas and Upapuranas: gdurl.com/NOE3 Both the Bhagavata Purana, presumably the Srimad Bhagavatam, and the "Daurga Purana", presumably the Devi Bhagavatam, are listed. For various reasons I think this particular chapter is an interpolation, but take it for what it's worth.
