They aren't really official college textbooks.  They are for my Web Scripting class this Spring semester.  Due to the class size(only 5 of us are signed up), it has become an independent study class, which means that there are not any set class times and we meet with the professor individually at any time to complete projects while we learn the material on our own.  Our professor has allowed up to purchases whatever books we want to to learn the material that is expected to be learned, which is will be the programming languages JavaScript, Perl, and PHP.  I just purchases these books via Amazon just about an hour ago.
