Literature is more complicated. The classification for Language & Literature is "P". After generalities, all literature is divided up by:
Literature (stories, novels, & poetry) are mostly kept on LG3, in classes PJ -> PZ. Below you can find very general listing of classification for browsing.
PL 2250 -> 3208 = Chinese literature
金庸, also known as Louis Cha, has written several novels. As an author he has a classification number of PL2848.Y8
This shows that he is a Chinese language author who began writing (or, at least publishing) after 1949. His family name is Chin (PL2848) and his given name is Yong (Y8).
But...why is he listed as "Chin"? His name is 金, which in pin-yin is "Jin" and in Cantonese pin-yin "Gum".
Until 2001, the US Library of Congress used a Romanization system called "Wade-Giles" where Chin meant Jin and Ch'in meant Qin. You can look at the Pinyin & Wade-Giles Conversion Tables for further details.
PR 1 - > PR 6126 - English literature from Britain

Here is the overall general classification by language:
