There are some people who think that reading printed books is better than Wikipedia or online reading.
These type of people are idiots.
This can be understood by judging the ratio of quality content divided by time spend reading it.
And of course, also the availability of information.
Also remember that vast majority of written information of humanity is online.
Printed books is in fact, a form of extreme inefficiency.
Remember that one printed book today is equivalent to a truckload of bamboo or papyrus scrolls 2000 years ago.
And today a laptop or iPad is equivalent to a truckload of printed books.
Now you have to consider the ease and availability of information in the reading media.
If you are using bamboo rolls or papyrus scrolls, does not matter how diligent a scholar you are, you will be getting 10 times less information than if you use a modern printed books.
Similarly, if you study or research using computers, it is 10 times more efficient than using printed books.
