I recently upgraded an iPad app that I use everyday (~$10.00 for the upgrade).  
I use ‘PDF Expert’ for all my PDF reference materials: data sheets, books, articles, equipment manuals etc.  
PDFs, like the 650 page Amtel328 data sheet, can be: searched, bookmarked, annotated, edited and sent to other apps or printers.  
The new upgrade allows you to:

- edit existing text - font/color/content/size/position
- add/move/resize images
- redact text
- link text to other page or WEB references.  
Of course, you can still annotate: draw/highlight/add comments/add text/add signatures/add and delete sheets/add stamps.  
I always sync my PDF documents to offsite storage for a backup.

I got rid of 300 pounds of data books from my shelves.

Can’t live without it!
