Penelitian ini membahas mengenai pengembangan koleksi anak di Perpustakaan Umum Kabupaten Bogor yang merupakan penelitian kualitatif dengan menggunakan metode studi kasus. Penelitian ini bertujuan untuk menggambarkan bagaimana pustakawan menerapkan kebijakan pengembangan koleksi, yaitu kegiatan seleksi, pengadaan, pengolahan, pemeliharaan, dan penyiangan di layanan anak agar dapat memenuhi kebutuhan pemustaka anak sehingga kendala apa saja yang dihadapi dapat diketahui. Peneliti menyimpulkan bahwa pustakawan mengadakan pengembangan koleksi berdasarkan kemampuan dan pemahaman mereka dari kegiatan seleksi hingga penyiangan. Pedoman tertulis tidak dijadikan dasar dalam melakukan kegiatan pengembangan koleksi anak sehingga kemampuan dasar pustakawan menjadi utama agar kesesuaian koleksi anak dapat tercipta. Tidak adanya pedoman tertulis secara jelas, keterbatasan anggaran dan terbentur dengan kebijakan yang ada menyebabkan pustakawan tidak dapat secara maksimal mengembangkan mutu koleksi anak di Perpustakaan Umum Daerah Kabupaten Bogor.
