Question

Propound on why a library is said to be the memory of the human race?

Answer 1

Yes a library is said to be the memory of the human race. It is because of the fact that library is the only place where thousands and thousands of books are placed from the beginning of the world to the prediction of the ending of the world, from cultures to heritages, from personalities to places of the world, from arts to science, from fiction to truth and so on. There is literally no subject or area of the world which is not covered in the books. People who wrote the books might have passed away years ago, but their writings are still alive as a memory in the library. So that is why a library is called the Memory of the Human Race

Answer 2

Let's look at the phrase "the memory of the human race?".

Memories are usually belonging to one specific human, and stored in their brain. The human race doesn't literally have a memory, so this must be  a metaphor.

This metaphor might mean what the human race, as a total, can remember and have access to.

So just like we remember what happened last Tuesday, the human race can find the information in a library about what happened in 1912- in this way, a library and a memory are similar, so a library is truly a memory of the human race.
