The most current list of Litecoin exchanges, originally from the Litecoin wiki, updated in December 2017 to remove nonfunctional exchanges:
There is a list of exchanges (and other businesses and tools) in the Litecoin wiki: https://litecoin.info/Service_Directory#Market_exchanges
There is a Norway exchange where you can buy and sell, it is called Justcoin
There is also quite new, but interesting exchange https://www.247exchange.com/ allowing to buy litecoins with credit and debit cards, bank transfers and cash deposits (400k locations worldwide). That I liked most, that they do not hold user's funds and there is no need to trade there - they will fund your litecoin account right after you will make a payment. Although I was upset that they limit first credit card purchases with about $100, the rates are better than at most other exchanges and instant delivery works great!
