Thank you Anirudh,
I did not know that Divya Prabandam is called Dravida Veda or Fifth Veda and I do not speak Tamil. Since only Yoga and Vedanta are popular in the West and available in my mother tounge I am not familiar with Vaishnava Traditions. Anyhow I like to read these scriptures.

There are more fifth Vedas
Mahabharatam is called as the fifth or the panchama Veda.
The Ramayana, also makes a claim to be the fifth Veda.
Similar claims are made in the Puranas, which claim to be the fifth Veda
The Natya Shastra, a text dealing with performative theory, also applies to itself the label of "Fifth Veda"
Other works that have been characterised as the "Fifth Veda" include, texts on ayurveda
