In a study of ESL students studying English in a university setting: ...the authors found that 68% of the students preferred learning through the use of hyperlinks, and that they "perceived the links as helpful in order to achieve better text comprehension, [they] ultimately found that there was no difference between the reading comprehension of those who learned through interactive websites and those who learned through books, it is interesting to note that the students still felt as if they had learned more through the use of the Internet. Carr also does not take into consideration e-readers and tablets, in which people read books, articles, and newspapers in electronic form, or people who listen to books on tape. The latter is especially beneficial to the blind and learning impaired. Besides reading Braille or having someone read to them, audiobooks may be the only source of reading material
