I am new to this site and hope to get assistance and guidance as I have just purchased an iPad 2 and don't really know how best to use it. I do want to download books. I prefer to find sites that allow FREE downloads. Are there limitations on the file format? Can you suggest websites offering FREE content. I have been to my library and they are very restrictive. The books reside for a very limited time. I am retired and often travel on lengthy trips and would like to have a few books on the iPad that will reside until I delete them. Your advice is greatly appreciated. I am interested in both classic books (no copyright protection) and also current and popular titles. I also want to learn how to best put photos on my iPad. Can you recommend apps that work well esp. for large now. of images.
