Dan if you use an app like Unrealbook, you can simply select a song you want to play from the book and then using the file menu, "export" that one song to your song lists.

So all you have to do is transfer the whole PDF fake book as one file, no scanning individual pages at all smile

It actually only saves a link to the page in the fake book, but it (the chart) loads exactly the same as if it were a normal stand-alone chart, and can be manipulated and notated as if it were a separately scanned chart too.

As for the OP, there are some free PDF readers, but not really suitable for chart reading. Some are also free from music publishers, but have "in-app" costs for charts that you HAVE to buy from them....

TBH, at $5.50 Unrealbook is a real bargain, and all totally free updates. You would probably pay more for a decent espresso!!!
