I have seen copies of the Hobbit in Farsi (but not LotR or Silm) actually available for sale online but nothing in Hindi, Urdu, etc. Sometimes it's hard to get hold of such copies to buy, even if they exist, if you live outside a particular country.
Harry Potter is easily available in Arabic. We have six volumes in our house belonging to my son. I've also seen at least six of Rowling's books translated into Urdu and Farsi. Anyone know or can venture a guess why those made it into translation before the Hobbit or LotR?

I have been collecting "foreign" Hobbits for a while, especially the illustrated ones. If you'd like to buy translations, you might want to try this link:
http://www.neko.com/ebayTolkien.html The site is updated every day and lists all the traslations of Tolkien available on ebay. Another helpful link for Tolkien translations is this one:
http://multilingualbooks.com/tolkien.html This online bookshop carries a number of titles from across the world. Also, the online Tolkien Shop (from Holland) is very good for European publications:
