Having just reviewed Follett’s suite of ebook-related products last month, it’s been interesting to compare how Mackin is serving up digital content they offer the pre-K–12 market, including the more than 37,000 unlimited, simultaneous access ebooks in its rapidly growing catalog. It’s especially interesting since lots of that content is available from both vendors. And, Mackin—like Follett—is scrambling to evolve quickly and cater to increasingly econtent-savvy customers in order to grab as much of the emerging school library ebook market as possible. It’s a market that—fuse finally lit—could blow up big-time any moment now, at which point the vendor with the most established platform is bound to win big.
