like...seriously? they really thought there was improvement to be made on the Library of Congress logo? Its a book...and its nice and iconic, recognizable. They said the new design gives a brand identity thats more "accessible"...what is not accessible about a book? I get that the library has more than books, but that doesn't really make the old logo any less relevant.
WHY change a logo which has served, embedded and part of the company's soul for over 40 years no less, especially if it was designed by someone like Vignelli.
