Despite freezing temperatures, widespread travel delays, and a Saturday snowfall, some 12,000 librarians, publishers, and authors gathered in Philadelphia from January 24 to 28, in Center City's Pennsylvania Convention Center. A highlight, as always, was the announcement of the 2014 Newbery, Caldecott, and Printz Awards, as well as a full roster of ALA Youth Media Awards. And though many more authors attend the ALA annual conference in summertime, we did spot a number of authors and illustrators on the conference floor, and we've rounded up some of the photographic highlights for you.
