Toddler bed

We're going to start training Naomi to sleep in her toddler bed next week. If anyone has brilliant advice on how to get an active toddler to stay in her bed and actually fall asleep, please feel free to advise. My main concern is that she loves to read and has a bookcase full of books in her room...I'm not sure she'll ever stay in bed if she can keep hopping up to grab another book! (Not unlike her parents, but it does make it difficult for maintaining parental-approved sleep patterns.)
