hello, do you have a persian books?? thanks....
At least in the bigger public libraries of Helsinki metropolitan area there are many books in Persian language. If your local library doesn't have many books in Persian, you can ask the librarian over there if they could order some books from other libraries for you.
You can browse the Persian language books in Helsinki, Espoo and Vantaa public libraries by choosing the advanced search here: http://helmet.fi/search~S9/X and selecting the Persian language from the language menu. If you want to browse all the available Persian books without restricting your search in any other way, you can replace query words by typing only two asterisks ** in the search field.
