Tizra Gets Logical

As those who regularly commute between the worlds of print and digital are painfully aware, important things are often lost in translation.  For example, digital people tend to think in terms of "physical" page numbers (the ones you see in your text editor as a document scrolls by on screen), whereas print people tend to think in terms of "logical" page numbers (Roman numerals for introduction and other front matter, Arabic for the rest, like you see in books).

For many of our customers, this hasn't been a problem, in part because we make it so easy for users to deep link directly to specific pages using standard URLs.

But for others, it can cause real confusion. Think of teachers assigning reading to their classes using multiple pagination schemes.

Now Tizra's added the ability for publishers to have it both ways: every page is linkable as always, but logical page numbering is also supported. That means when the teacher says "go to page viii in your textbook," it means the same thing as when they post this link in their Learning Management System.

The feature is simple to use, because it takes advantage of the page numbering features already built into the standards for the PDF file format. Once the feature is activated on your Tizra site, any PDF you load with logical page numbering in it will automatically be displayed with that numbering in Tizra's online reader and tables of contents.

How you get the required information into your PDFs will depend on your software, but it's generally a matter of a few clicks. For example in Adobe Acrobat, you can select a range of pages in the thumbnail view, then right click to pop up the page numbering dialog, which lets you specify how those pages should be numbered.

Once that's done, Tizra can import the logical page numbers and display them on your site, as in the table of contents below (Figure 1).
Figure 1

Click on the table of contents heading Introduction (Figure 1, above) and the Tizra online content reader (Figure 2, below) displays Page iii (of 10), where "iii" is the logical/printed page number and "10" is the total number of pages in the PDF. 
Note the printed page number circled in the bottom right-hand corner of the page.

Figure 2

You can even jump to logical page numbers (as always, if users have access to the page). For example: entering "iv"  in the Go field (Figure 3) will bring the reader to logical/printed page number iv.

New Mobile-Optimized Template Simplifies Site Design

Pre-designed templates are increasingly popular as a quick way to get new Tizra sites launched, or to refresh the design of an existing site.  A key driver in both cases is keeping up with increasingly high user expectations for ease of use and visual appeal, particularly on mobile devices. To address these needs, we’ve released a major upgrade to our Bootstrap-based responsive design template. The new version makes it much easier to customize with your own colors and logo, improves mobile interaction with the latest version of the Bootstrap framework, and adds numerous other visual and usability refinements.

Existing Tizra customers can try it out now by selecting the “Bootstrap Responsive Template” in the PRESENTATION area. Or if you’d like to see a quick preview, take a look at this demo site…

Using XML to Create a Better Online Reading Experience for the American Payroll Association

Congrats to the American Payroll Association on their recent launch of XML-based publications on Tizra!  Thanks to this collaboration, APA's authoritative books for payroll professionals are now available in crisp, reflowable HTML, creating a user experience that feels like a truly digital native product, rather than a conversion from print. XML-based publishing also creates a better mobile reading experience, supports more precise search and navigation, and opens the door to better accessibility for users with low vision and other disabilities. Our partners at Scribe did a great job supporting APA through the process of producing the XML for loading into Tizra, and we’d definitely recommend them to anyone interested in such a transition. It’s hard to overstate what a big step forward this is for Tizra as a platform and a company. XML has long been planned for in the product's architecture, but now for the first time, we have a working example that demonstrates the power of c…

What Einstein Taught Us About Searching Inside Publications

When the Collected Papers of Albert Einstein went live on Tizra a few years ago, it was a huge step forward. Suddenly, anyone anywhere could search and access the output of one of the 20th Century’s great minds…from love letters to breakthrough articles that changed how we think about the nature of time and space. But the project also showed the limits of traditional tools for searching within large, complex publications. These limits sparked a collaboration with Princeton University Press and Einstein Papers Project editors, which this year resulted in a dynamic new search interface, which we’ll be demonstrating in a Webcast Friday, December 15 at 1pm ET. The interface not only makes it easier for Einstein researchers to home in on relevant content on both mobile devices and desktops, it points the way toward faster, better searching within a wide range of publication types, from reference books to periodicals, technical documentation and standards to textbooks.
