If you are interested in children’s literature and reviewing and publishing, consider applying for the Horn Book internship. As Roger Sutton notes, maybe someday 7 Impossible Things Before Breakfast will interview you like they did Alvina Ling (which you should also check out–good interview). (Alvina, I had no idea you also interned at Horn Book. Probably because you were already in New York by the time I was interning, given that I moved to Boston when L,B was consolidating to New York.)
Even if they don’t interview you someday, it was a great experience and I learned a lot about the review selection process and was even given the opportunity to write a review for the Guide. Some interns just work for the Guide, some just for the Magazine, and some for both–I worked for both, and it was a great experience. If you’re in the Boston area, check
it out. You’ll meet a lot of good people.
