Today, I went to the national diet library in order to find some references for the presentation. This was the first time I went to the national diet library but I found their very pleasant for me. There was high ceiling and some stained glasses. Also, the system introduced for users was so automatic. Most of the books were not available for the uses directly; first, users resisted the book the wanted to read via computers. Then, users pick up the books which they have registered after they got the announcement.
