Who can amend this short essay for me?

Who can help me amend this essay for me to make it more fluid read and idiomatic? Thank you.
The topic is"Describe one way of life in your country has been changed and why it is beneficial". My answer is as follows:

One major change in people’s way of live in our country is the prevalent use of computers in study. Computers make study much more efficient and convenient.

In the past, when people wanted to learn about some new knowledge, they had to read related books or magazine. It took a long time to identify what books they needed and a longer time to find out the knowledge in the books. With computer, however, you can search what you need immediately. Thus a lot of time is saved.

What’s more, in the past, people could only get limited kinds of books in the libraries or bookstores nearby. But nowadays, the wide spread of internet makes various source of knowledge from all over the world available to people. Therefore, it’s more   convenient for people to study now.
