1. Copy the PDFs of each catalog you want to add to your device to your computer’s desktop

2. Open iTunes on your computer that you use with your mobile device

3. Connect your device to your computer so that iTunes recognizes it as connected

4. Click and drag one of the PDF catalogs from your desktop and release your mouse button while the PDF is over the “Library” area in the top left of iTunes

5. As soon as you let go of your mouse the PDF will begin converting into the format that your device will recognize as an ebook (this may take a couple minutes for the 300+ page books)

6. Once the conversion has completed your new e-catalog will appear on your “books” tab in iTunes

7. Once you’ve dragged, dropped & converted all of the PDF catalogs you want on your device you just need to click on “Sync” on the books tab and they will be transferred to your device

8. Now simply open your iBooks app on your device and you will see each of your converted e-catalogs ready for viewing (Open each book once so that all the pages can load into memory – faster loading when next opened)
