I do not know if Jan E.M. Houben was intending coverage of Indian literature in other Indian languages too and whether he intended the modern period too.
 
If he did, this is huge in various Indian languages of various periods, particularly modern period.
 
Some posts covered Hindi and modern period.  

  I would share from Telugu. But was that intended?
