As some people may know, I have studied Polish language mainly on my own and mainly by reading and listening to books.
While I can't say enough about how well this approach has worked for me, one of the problems has always been the lack of a large selection of books in the Polish language and the cost of purchasing them. In the States, only a few books (really popular ones) are available in bookstores and only old, obscure books are available at the library.
However, this afternoon, I was at the most amazing place in Poland so far... the library! ;-) There are thousands of books in Polish and they are all for free!!
I just got my library card and a few books. Life is good.
