Book Donation

I donated some books to a university library of an university. I have many books on my bookshelf. When While I was arranging/rearranging my books yesterday, I decided to donate some of them. So I searched on the Internet and found a library which that accepts donations. I packed the books and then sent them off to the library. [不必多提, 首句已經告訴了我们]

寫得不錯, 沒有什么語法大錯誤.
