Since my childhood, libraries have played a role of great important in my life. When l was a pupil,I regarded on my every trip to the school library as an adventure.I enjoyed my stay there when I could read various book l was interested in. It was for this reason why I decided to volunteer at a library. At first I had difficulty remember where each book should be shelved and I got used to doing so soon with the help of a kind librarian. Working in the library might seem bored for most people. However, it was rewarding experience for me. It has not only developed my ability to read,but also help me make a contribution to society.
