This paper deals with library automation and book detection using deep learning which comes under field of computer vision 1. In order to automate a large Library where finding a book is a tough task, this paper shows a solution for it. Here we detect the required book with the help of deep learning concept through MATLAB Neural network toolbox which can pick the particular book with the help of a mobile manipulator. Convolutional neural network used is Alex Net which can detect around 1000 classes.Deep learning is a part of machine learning in which a network learns how to classify objects from texts, Images, and sound. The first part in the name Deep Learning i.e. "deep" means number of layers in the network-A network is said to be deeper when it has many layers. Generally neural networks contain 2 or 3 layers, while deeper networks contain hundreds of layers.The device used is a rover with capability of holding a book with its fingers. It also consists of a camera which scans through the books whose output is then analysed by a neural network.
