Puranas

The word Purana (/pʊˈrɑːnə/; Sanskrit: पुराण, purāṇa) literally means "ancient, old", and it is a vast genre of Indian literature about a wide range of topics, particularly legends and other traditional lore. The Puranas are known for the intricate layers of symbolism depicted within their stories. Composed primarily in Sanskrit, but also in Tamil and other Indian languages, several of these texts are named after major Hindu deities such as Vishnu, Shiva, Brahma and Shakti. The Puranic genre of literature is found in both Hinduism and Jainism.

Etymology
Douglas Harper states that the etymological origins of Puranas are from Sanskrit Puranah, literally "ancient, former," from pura "formerly, before," cognate with Greek paros "before," pro "before," Avestan paro "before," Old English fore, from Proto-Indo-European *pre-, from *per-."

List of Puranas
There are 18 puranas:

Brahma Purana
Sometimes also called Adi Purana, because many Mahapuranas lists put it first of 18. The text has 245 chapters, shares many passages with Vishnu, Vayu, Markendeya Puranas, and with the Mahabharata. Includes mythology, theory of war, art work in temples, and other cultural topics. Describes holy places in Odisha, and weaves themes of Vishnu and Shiva, but hardly any mention of deity Brahma despite the title.

Padma Purana
A large compilation of diverse topics, it escribes cosmology, the world and nature of life from the perspective of Vishnu. It also discusses festivals, numerous legends, geography of rivers and regions from northwest India to Bengal to the kingdom of Tripura, major sages of India, various Avatars of Vishnu and his cooperation with Shiva, a story of Rama-Sita that is different from the Hindu epic Ramayana. The north Indian manuscripts of Padma Purana are very different from south Indian versions, and the various recensions in both groups in different languages (Devanagari and Bengali, for example) show major inconsistencies. Like the Skanda Purana, it is a detailed treatise on travel and pilgrimage centers in India.
