Nearly a third of adults in the United States now read books on a tablet or e-book readers.
Only 13 per cent of respondents who currently don't read books electronically said they are "very likely" or "somewhat likely" to start doing so in the next six months.
Some 77 per cent said they are not likely to do so, with half of the group saying they almost certainly won't.
The Harris Poll results, though, might not be reflective of actual user behavior. Many respondents have in the past suggested they would not use e-readers, but their behavior is not congruent with those sentiments.
