The lecturer casts the doubt on the main assertion of the passage that digital libraries offer us various benefits. According to the lecture, advantages of digital libraries are not as much ideal as the reading maintains.
First of all, the speaker mentions the possible inequality to access the information caused by one's economic condition, while the reading only focuses on simple accessibility of books provided by digital libraries. The speaker emphasizes that people need to possess their own computer to use digital libraries, which means poor people cannot use digital libraries easily.
Second, the lecture rebuffs the reading's idea that digital libraries are time-saving by following reasons. Even though digital libraries would save the time to find a book from shelves, it is also inefficient to read whole book to find a sentence that we need. Compared to scanning that we can do with anologue books, it is much time consuming.
Last, the man of speaking does not agree with the assumption of the passage that digital libraries dedicate to world's intellectual property, because digital libraries would not pay back the reasonable compensation that should be given to authors. For this reason, digital libraries are likely to degrade the qualities of intellectual products over all worlds.
