Ok, I'm sorry to be the negative guy here, but there is some thing terribly wrong in the article. The Library is not an array. It's more of a hash table than an array. You first calculate the hash for what you are searching for, go to that location, and search there. Once you stop thinking of a library as an array, and be more realistic, you could understand why what the writer is talking about doesn't make much sense.
