Textbooks are heavy.
Both in terms of weight and price.
The expense of textbooks outpace of everything, literally, including the tutorial classes. But students have no option but to buy them.
However, cloud-based textbooks can solve the problem. Simply put, the digital content is less expensive as compared to the printed content. It has the ease to create duplicate copies and yet other than the cloud space, it does not incur any extravagancy.
When observed at a different angle, the content is first researched, then verified, then written, then edited, then printed, then edited again, then printed, then updated with the new content, then edited, then updated, and oh so costly.
But with digital content the case is quite simple. You research the content, you verify it, then write it, then edit it, publish it, then edit again, then publish it, then update it, and publish again, and again, and again.
See much cost effective. All print costs are safe-pocketed with you.
This is a digital learning for you.
Also, when a material is to be shared with the entire class cloud is the best solution that I can think of.
It is as simple as doing it to one and the reach is undebatable.
