I also tried library classification, but because of the great difference in the number of books under different types, I wasted some shelf space.

At present, my classification and placement methods are as follows:

1, on the premise that the bookshelf is a whole wall type;

2, according to the vertical classification of countries and regions, according to the horizontal classification of book types.

According to their own library collections, they are divided into Asia, Europe and South America, as well as China, the United States, Britain, Ireland, France, Germany and the former Soviet Union. Among them, Europe is divided into northern Europe, southern Europe and eastern Europe from left to right in the bookshelf.

Horizontally, it is divided into social science and literature, and further subdivided in these two parts, such as fiction and non-fiction, history and geography.

The advantages of this are:

1, the preferences and disadvantages of buying books and reading are clear at a glance;

2. Establish the concept of creative style and characteristics of each region within the reading scope;

3. It is convenient to remember the nationality of unknown authors;

4, especially good at finding books.
