Technical Services and Collection Development for Children's Libraries

What has technical services to do with collection development for children's collections—or any other kind of collections for that matter? Isn't technical services what happens after selection decisions and other collection development plans are complete? Don't the technical services staff simply execute the decisions? These questions are familiar to any technical services librarian who ventures across the invisible line into the world of material selection and collection development, and onto the toes of subject specialists, bibliographers, reference or children's specialists, who inhabit that world. They rule their domain with clearly defined credentials supporting their hegemony, largely ignoring the mundane concerns of their technical services colleagues.
