If you have tried adding PDF files to iTunes for syncing with iBooks on your iPad, iPhone or iPod Touch then you will know that this isn’t as easy as it sounds. However here is a method which should make it easier for you to send any document or even web page straight to the Books section of iTunes for syncing with ease.
To get iTunes ready is simple. All you have to do is open your Applications folder, and make an alias of iTunes by control-clicking its icon and selecting ‘Make Alias’.
Now drag your newly-created alias and drop it in [Your Home folder] → Library → PDF Services. What this does is adds iTunes as an option when you select the PDF button in a Print dialog.
If you did everything correct, then when you click the PDF button under Print, it’s going to say ‘iTunes alias’, which isn’t very informative. So the last thing you will want to do is rename the iTunes alias in the Finder to something along the lines of ‘Send PDF to iTunes’ or ‘Add PDF to iTunes’ and the menu item in the Print dialog should update next time you open it.
Now whenever you have a document or web page open that you’d like to read in iBooks, all you have to do is go to File → Print, then click the PDF button in the lower left and choose your menu item for iTunes. The document will be saved as a PDF and sent straight into the Books section of your iTunes library.
To test if it was really added to your Book section, just open iTunes, and check if it was added.
