For those of you that remember the old library, this one blows away the old one in most areas. I do find this one harder to concentrate in - the tall ceilings, coffee shop, etc. all hurt to make this less of a library and more of a large Starbucks with books.
Honestly, I prefer the old library to the new building, however, I like the new building with teh new tech and the people that are there. They do care and will help, even if the subject is archaic and obtuse.
