My older brother, John, is the Director of Public Services at the Cleveland Public Library. I went to visit him today and I remembered that our class inquired into a system in the library. Do you remember what that system was and how it works?

Hello everyone. I am sure you are already enjoying your break! I am posting a picture of myself, can you guess where I am? Leave me your guess in the comments section. If you would like to email me a picture of where you are, I will post it and we can try to guess where you are for break! Happy Holidays!
