Put simply, E-Books are electronic books that can be read with free software on a computer screen or printed out to paper. Our E-Books are supplied in Adobe Acrobat Reader format (PDF) that you can download for free and store on your PC. E-Books offer a high level of interactivity not possible in print editions. This makes E-Books the perfect medium for our science project and experiment guides; because you can immediately search or skip to information or resources at exactly the moment you need them.
