Color e-paper is coming

In some ways, this is news like it’s news that Apple is working on an iPad 3 or Google is working on a new version of Android. Of course they’re working on new products; of course companies are working on color e-paper displays. The conversation really gets interesting when there are devices to look at.

Electronic Paper Display

I’m using e-paper as a generic term for display technologies that try to mimic the experience of reading a printed page. Generally this means they rely on natural ambient light instead of using a backlight. But beyond that similarity there are big differences between manufacturers.

E Ink’s Triton display

E Ink is the company that builds the displays in the black & white Kindle, Sony and Nook e-readers, among others. Look at all the devices using E Ink’s screen technologies in this table of e-readers (6″ devices especially). E Ink is practically running the table. This is usually what people mean when they talk about e-ink devices, since it’s what they’ve had direct experience with.

E Ink displays use microcapsules….just watch this video from E Ink that explains how they work (start at the 45-second mark if you just want to see the explanation).The screen flash that happens when you turn a page on a Kindle makes a lot more sense, seeing this. Those microcapsules have to rotate into place to display an image or page of text.

This is true of the display in the Kindle, and it’s true of E Ink’s new Triton color display. Here’s a demonstration on YouTube (skip the first 30 seconds) that shows that familiar flash. Video isn’t coming to displays that use microcapsule technology, but devices that use this tech are on the horizon. The ECTACO jetBook Color is set to ship in January 2012. $500 gets you this color 9.7″ touchscreen E Ink display.

Qualcomm’s Mirasol display

For a different approach, Qualcomm’s Mirasol display uses pixel tech more familiar from the LCD world. Watch their explanatory video here. Qualcomm creates tiny squares (tech folks call them sub-pixels) that reflect light of different colors: red, green, and blue, just like a laptop’s display. They’re so tiny that the combinations of red-blue-green (and black, when not electrified) appear to be a single color to the eye. A set of red, blue, and green sub-pixels is called a pixel.

This technology can refresh what’s on the display more quickly. There’s no flash. Their demo video makes it look more like a tablet, and it is in fact running Android. They boast that it can show 40 frames per second (DVDs show 30 frames per second), but watching a demo of the display being used (start at 1:15). The touchscreen does not look very responsive. It can play video, however (start at about 3:05), so I don’t know if the slow response is related to the display or the processor. Its price is about $300.

Either way, neither the Triton nor the Mirasol displays are iPad-fast by quite a stretch. The quality of their color displays also depend greatly on the ambient lighting conditions. The last Mirasol demo, for example, has a bright window behind the device. That’s just about the worst lighting you could choose, which is why the colors look so washed out.

So color e-paper is coming soon. If these are the technologies available for it, will people want it when it comes? I think it will take more than an illustration or two in a book to overcome the cost and limitations of these displays.


Who speaks for your library?

This past Wednesday, I gave my first SWONtech News webinar. Log in for an hour and you’ll find news and research that relates to libraries. I’ll be blogging about some of the stories that I covered there, especially since the story topics (like e-readers and ebooks) will continue to develop for a long time to come.

One topic I discussed was social media use by libraries. We looked at screenshots of Twitter’s redesigned website. For new users, especially, it makes important features (@Replies and #Trends) more visible. I encouraged (pushed?) listeners to engage on Twitter in a professional capacity. By that I mean connecting to peers and patrons.

While I was speaking someone typed into the chat bar, “Our library doesn’t have a Twitter account.” Believe it or not, this may be good news. Publishing announcement-type posts to Facebook from the library as a whole might be done by several different people on staff. In that case, it’s the news that’s important, and not which person posts it. These announcements are important, but they aren’t very personal, and it’s not very surprising that they don’t receive many comments.

You can use Twitter to supplement announcement-type posts by tweeting as a human being. Use your picture in your profile, not a picture of your library. Follow other librarians. Follow news organizations. Retweet (share) the information you find, and be open to sharing some of your personal responses and activity. You represent your library, but you aren’t its official and only voice.

Who speaks for you library? Lots of people do. Libraries are part of communities of people, whatever type of library they happen to be. Twitter is an easy way you can speak for your library as an individual. If you’re willing to field comments and questions (whether directly or simply with links to current information), your 140-character tweets can accomplish a lot. They can also help patrons build relationships with libraries–with the people who work there and not just the building they visit.

Tweeting from your own account, instead of the library’s, is a great way to complement the communication efforts of your library. Yours isn’t the only voice speaking for your library, but it’s a voice that counts.


Libraries buy books. Sometimes they’re digital.

I’ve been visiting libraries with our E-Reader Sandbox program, introducing the devices and ways to use them. When we get to the section on checking out ebooks from the Ohio Ebook Project, I see lots of frowns when I describe the waiting lists for some titles. At the moment, for example, there are 163 patrons on the waiting list for The Help, even though the page shows that the library has 108 copies. “It’s just like with books,” someone says.

But They’re Digital

People know that the ownership model isn’t the only option when it comes to digital files. I don’t know much of anything about Netflix’s inner workings, but I know they don’t have to buy a “copy” of each TV episode I want to stream. They have licensing agreements in place. No one has to wait for me to finish watching Mr. Bean “eat” steak tartar to watch it themselves. I’m not interested in those licensing agreements (unless one ends and I lose access to content I like). As long as it just works, that’s all I need to know.

If patrons are confused about the way ebooks and libraries work in this regard, it’s not necessarily naiveté. Maybe they think of ebooks like text files that can be duplicated endlessly with a simple keystroke. But maybe they’re thinking of other access models. Count me among the crowds who would like ebook access to newly-released titles to be as open as works in the public domain hosted at Archive.org. How should I know that the library’s access doesn’t work like that?

Welcome to the Real World

That kind of access is a pipe dream, but ebook licensing is among a number of library functions that often take place invisibly. Sometimes invisibility is good. As a patron, I can ask for a book at the counter and it’s handed to me, or it’s put on hold and delivered to my branch, or the library considers purchasing it. Maybe Inter-Library Loan deserves its own episode of “Modern Marvels,” but on a daily basis, that process’s invisibility is fine with me.

Conflicts arise when people have expectations that aren’t met. “I have to wait behind 163 people? Wait, 164? I thought I could just download it now.” We can help people set their expectations by educating them before they’re disappointed. Tell your patrons how ebook lending works, and make that part of your pitch. When Kindle-format ebooks came to Overdrive, libraries quickly sent out the word on their websites and Facebook pages. “Now available” was true, but it only told part of the story.

Limited availability is bad news in some sense, but it’s also important news. When you read a Black Friday ad, it’s important to find the footnote that reads “Minimum 2 per store.” You’d probably prefer that number to be 500, but you’d definitely want to avoid waiting in line all night to be the thirtieth person to find the item’s out of stock.

Libraries buy books. Sometimes they’re digital.

Maybe this six-word summary doesn’t say enough to communicate the essential message, and maybe it doesn’t accurately describe your system. Find the simplest explanation you can. Use a footnote if necessary. Whatever explanation you use, you’ll need to use it a lot, in lots of locations: your website, your Facebook wall, your entryway hall. Find ways to keep the message fresh. You don’t want to bore people who have seen the message twenty times already, but you don’t want to miss the patron who’s finally coming to see what the ebook buzz is about.

Create your own documentation on the topic and keep linking to it. Don’t rely on Overdrive’s site to explain it. Help set patron expectations early and often, and they’ll be better able to move past the bad to the good news about ebook lending.
