I have added a new Audiobooks section to the Resources page. This page includes links to other learning Mandarin courses. The Pimsleur series is one of the most popular language learning systems (for any language) and was one of the influences in the design of my course. The various levels and versions are now available for purchase here. Links to other courses are also available for those looking for more material to supplement your learning here.
While they are being sold by third party vendors, CLO gets a small commission for referring them to you. I will also be adding Google Adsense ads to the Music pages in the near future. Revenue from these ventures will be used to enhance the free resources on the website.
