method is time taking but can be worked to make it easier and also possible to make extension for coursesmart with great features...

I think pdf file size will be much larger due to images but u can use ocr tool to convert in searchable pdf and help u to reduce size of file. There are many threads and videos for it.... also one cant remove coursesmart logo as well but it is not much issue as you are not doing any illegal things like sharing or piracy on net....

main purpose of this etextbook is to get at low price and read at convenience without any problem if internet access is not available....
