Notable PDF is getting there

I’m not sure if I mentioned it here before, but last year I got myself a Chromebook (a 1st gen. HP Chromebook 14), to replace my aging and increasingly decrepit (or should I say decrapit) iPad 1 as my main portable note-taking and web-surfing machine. I quickly became a Chromebook convert, especially after I discovered how easy and convenient it is to use Chrome Remote Desktop to access my Windows 7 PC, thus always having my office with me.

The only area where my Chromebook and Chrome OS were lacking and where my iPad 1 (with the GoodReader app, for instance) was still superior was PDF annotation. It was certainly possible to read a PDF on a Chromebook but there was no satisfactory solution to annotate a book-sized PDF, both online and offline, and then be able to export the annotated PDF file or the annotations themselves. Not until Notable PDF appeared on the scene that is. I have been using Notable since its beta days on and off, but until recently I kept running into problems that made me return to annotating on the PC or on my old iPad.

However, in recent weeks I checked back again and I was very pleasantly surprised that Notable have ironed out some of the obstacles that kept me from adopting it permanently. Finally I was able to download my annotated PDF file and open it in PDF XChange Editor on the PC, and I saw all my highlights and annotations in place. It is still not perfect, as the highlights in XChange Editor show up as some kind of colour overlay rather than XChange’s own native highlights, but hey, I can live with that. What is more important is that I am now able to read and manipulate my Notable annotations in XChange Editor.

Moreover, Notable has some tricks up its sleave that give it a distinct advantage over some other PDF annotating options. Notable PDF is a Chrome browser extension, which makes it cross-platform on desktops, as long as you have Chrome installed on your other machines.* It appears to save the annotations in the cloud, which means that it doesn’t matter where you keep your file, and how many copies of your file you have, it will sync the annotations to that file (and its copies) across all the browsers. You can even have two different copies of the same PDF file open in different machines in Chrome, and the annotations will sync live and automatically, in front of your eyes. This feature of course would be very useful for collaborations, as you can see instantly what others are commenting on that file.

To me, this feature means more flexibility. For example, the copy of  the PDF file I’m reading is saved on the hard drive of the Chromebook. When I’m offline, the annotations are saved offline, and then synced when I’m back online. However, I also have a copy of the same file on my Google Drive account in the cloud, and if I’m on another machine, let’s say a PC at work and I do not have my Chromebook with me with the original file, I can just open the copy from Google Drive, and Notable recognises it as a copy of the annotated file and it populates it with the annotations saved on their server. I find this rather clever and very useful.

In any case, I just wanted to say that I’m happy now to include Notable PDF among my favourite apps and recommend it to others, especially Chromebook users. While it’s not entirely perfect for my needs (I wish the yellow highlights could be converted to native highlights in PDF XChange Editor, so they can be extracted from there), it is probably the best option for PDF reading and annotating on Chromebook today. Also, I have been following them for the past year, and development has been on-going, so I am hopeful that Notable will continue to be improving.


* Having just looked at their website more closely, it turns out now they also have a web app, so in fact you can use their service on any browser, not just Chrome.

Kindle is not for me

Surely I must count as some sort of a dinosaur, as it was only today that I’d purchased – and then promptly returned – my very first Kindle e-book. I managed to avoid Kindle up until now by being able to find paper books or online e-books at my university library for the titles I needed. But today I urgently needed a book that wasn’t available at my library and I couldn’t find it in any other electronic format.

I did see the book before in some kind of a PDF format for a reasonable price at Google Play, and I naively assumed that it would be waiting for me there in my moment of need. It turns out that e-books can sell out too (how exactly, I don’t quite understand), as the PDF was gone from Google Play and is nowhere to be found on the net.

The Kindle version of the book I was looking for was slightly cheaper than the paperback, and if I bought it I could have it instantly, so I took the plunge and purchased it. I downloaded a copy to my “Kindle for PC” app, and another copy to the Kindle app on my iPad. But as soon as I started reading, I began to run into several disappointing surprises.

First, there was no real pagination for this academic e-book, which meant that I wouldn’t be able to reference quotes directly. I was amazed that after all these years of kicking around, the Kindle people still haven’t solved this problem.

I also found it inconvenient that when I carried out any sort of operation with the e-book such as a simple search, Kindle would re-flow the text and it would end up looking different every time. The highlighted text with my note that I expected to find at the top of the page ended up at the bottom of the page and so on. Annoying. I need to have a sense of where stuff is in the book that I’ve already read and made a note of. Shifting its position around just makes it more difficult to comprehend an already challenging academic text.

Then I discovered that there was no direct and easy way to export my highlights and annotations from either the PC or the iOS app. The only way I could get any quotes or notes out was if I enabled an external clipboard capture software and copied each quote and note individually. I was ready to put up with that until after an hour of copying and pasting Kindle had kindly informed me that I had reached the copying limit set by the publisher. What? I’ve paid for this book, I should be able to copy out anything I like from it for my personal use, just like I can do with a paper book. I was starting to get angry.

The “icing on the cake” was when I had enough of reading on  the PC and I decided to carry on in my armchair using the iPad. When I loaded the Kindle iOS app, I fully expected to see my highlights and annotations that I had created on the PC app and which had been synced with the Amazon cloud. But after several attempts at reloading and refreshing, my notes simply didn’t show up on my iPad.

Perhaps some of the above problems had to do with me being a Kindle novice and missing some of the features that may have solved them instantly. But I just had an overwhelming feeling of being underserved and constrained by both Kindle apps and the entire platform. Both apps are very feature-poor compared to such excellent PDF readers like GoodReader or PDF Expert. I could think of two possible reasons for this. 1) Amazon can’t be bothered about the academic market that needs page numbers and annotation sync and export, or 2) it is some sort of an underhanded effort to force you to buy an actual Kindle device, where I presume at least some of the above issues have already been resolved.

Whatever the case, I’ve returned my first Kindle e-book and I will avoid buying another one, if I can help it. And I certainly won’t be buying a Kindle device any time soon. I’d rather read a good old PDF file on my iPad any day!

P.S. (12-Apr-2013):

Another shortcoming of the desktop PC Kindle app is its inadequate search function. I did a search for a single word in my e-book, and Kindle returned the suspiciously round figure of 100 results. I went through all the 100 results and then repeated the search. Not only did I get a different figure the second time (99 results), but they included results not contained in the previous search. When I manually flipped through the rest of the book, I found several occurrences of the search term that were simply not found by the Kindle app in either of the first two searches.

Together with everything else I mentioned, this makes the Kindle PC app – in conjunction with the iOS app – unsuitable for academic reading (at least in comparison with the tools available in PDF readers such the aforementioned iOS apps and PDF-XChange Viewer on the PC).

P.P.S. (12-Apr-2013):

Out of curiosity, today I had installed the PC app for NOOK Study and downloaded the same e-book (in whatever format NOOK uses) that I tested with the Kindle app. NOOK Study is directly targeting the academic audience, so I expected it to be more sophisticated. And it was, to some minor extent. For one, it allows you to export your annotations in .doc and .txt format, which would work for me. But I still found it far inferior to the PDF readers I use. I wasn’t able to test the search function because, as NOOK informed me, they were still building the search index for this book, and the search function would be available at some point in the future, depending on the size of my library. It all sounded a bit too tentative to me.

However, the problem of the page numbers has not been resolved. NOOK did provide the page numbers, but they were not the same as those of the paperback, which they claimed to have used for the e-book version. Basically they had started numbering the pages from the electronic table of contents that they had inserted in front of the cover of the scanned book, and then they kept on counting all the pages for which there weren’t even page numbers in the paperback. For this reason all the page numbers had shifted. This wouldn’t be a problem if the text of the book had not been reflowed, as I could have just recalculated the pages myself. But unfortunately NOOK re-flows the pages, meaning that the pages become meaningless and useless for the purposes of academic referencing. Too bad. PDFs it will be…
