As I researched on the web, there are no stock of the book that I was searching in book stores website. But it was needed to write my thesis. So I had to borrow from library.

As our library lends the book during summer vacation, I can borrow it about one and half months. I wanted to borrow two book, one of which was in Komaba. So I went out to Komaba to borrow.

Unfortunately, the season that we can borrow more than usual hasn't come in Komaba library. So this time I borrowed as usual, then I will take measures to borrow more.

As I was tired, I had asleep after having lunch. Then I started writing.
