Reader Rabbit's Reading Development Library is a series of four edutainment games from The Learning Company as part of the Reader Rabbit franchise. The first two games were developed in October 1995 and the last two were developed in 1996. The products make use of interactive storybooks based on fairy tales to help early readers broaden their reading, vocabulary, writing and word recognition skills. Each number in the title corresponds to the reading level of the reader they are aimed at.
