I use my iPad for many different purposes but having it as a portable reference device is a big benefit. Besides creating my own PDF documents and storing them in either DropBox or iBook I also collect PDF’s from other sources as well. If you are using your iPad to do research on the internet using Safari as your browser and you come upon a PDF download you can now not only display that PDF in Safari but also save it to your iBook library for future reading/reference. Once you have the PDF loaded in Safari notice in the upper top right of the screen that you have a Open in “iBooks” button choice. The PDF will be immediately transported to your iBook App and displayed on the screen for you. If you exit back to the Library you can then Edit and Move the new document into the “Collection” that you wish it to reside. While it is displayed on the screen you have the ability to print or email it or, of course, just sit back and read it.
