Marc Blaustein, art director for the library system, confirmed to the New York Times that the old logo, with white lines on a circular black background, “had a hard time maintaining its detail as it shrank.”

The strong lines on a vector format mean the new logo can be scaled to a range of sizes, especially prescient in the internet age, when as many people are likely to see the logo on a digital screen as they are in print.
That's Right,
