We are experimenting with display styles that make it easier to read articles in PMC. Our first effort uses eBook readers, which have several 'ease of reading' features already built in. These PMC articles are best viewed in the iBooks reader. You may notice problems with the display of certain parts of an article in other eReaders. Source.
