International Data Group (IDG) did a study to learn the amount of digital information produced by individuals and organizations around the world. According to their report , the amount of digital information produced is equivalent to thousands of tons of books or comparable to 12 towers that cover the distance between planet earth and the sun.
Every day, individuals share more than 100 billion of MP3 files, and YouTube disseminates 100 billion videos every 24 hours. In one year people take more than 100 million pictures with their cell phones and 150 billion pictures with their digital cameras.
The storage unit that has been used is the gigabyte, but because of the large amounts of information produced, very soon we will see a new unit called an exabyte or the equivalent of 100 billion gigabytes. When this storage unit is exhausted, we will use zettabytes that will correspond to 1,000 exabytes.

Libraries are going to stay around, but we will have to reinvent ourselves to better serve our patrons.
