I just got a new curriculum for my kids and the teacher guide is too big (117MB) to upload to Google Books where I usually keep teacher guides. I need a PDF solution that prioritizes a seamless reading experience across devices and platforms, with annotation being a bonus. I don’t generally need to write on my teacher guides, but it would be nice if I could. I want to be able to pick up any device, open the app, open the book and be on the same page I was just on on whatever other device I had opened it last. But also with easier file management than trying to upload things to Amazon to use the Kindle app.
Not sure this will help, but years ago (before paying for Adobe Acrobat Pro DC) I used a site called SmallPDF to compress large PDF’s to more manageable sizes. Might be a temporary fix for now…
That worked! I now have a 37MB teacher guide.
I’ve been exploring PDF readers which allow for stylus notes.
PDF Annotator is a paid software package which serves as a nimble reader and also allows seamless stylus interaction; you can draw all over your documents. If you upload the marked up version to a central cloud address, then it would presumably be available to anybody else with the same reader. You can check it out here, (there’s a 30 day free trial period if you want to give it a look):
I think they might have reduced prices for educators.
Then there’s XJournal++ which is a free and open source version of the same idea, but I found it a bit buggy (strange scrolling behavior when you use it with a touch interface):
They also have an on-line version which sounds like it was designed to serve in exactly the capacity you are asking about, in terms of accommodating many users…
-Maybe that one works better, but I’ve not tried that version out.
Hope that helps!
