You may find OCR (optical character recognition) software to be quite handy. This software provides the benefit of making scanned text documents very accessible. With this software, your scanned documents can be searched, copied and edited in Adobe Reader.
Open Adobe Reader.
Click "File," then "Open." Search for a scanned document in the pop-up window, select it, and click "Open."
Select the "Documents" tab, and select "OCR Recognition," and then select "Recognize Text Using OCR."
Select the number of pages you wish to apply OCR to in the "Recognize Text" pop-up window.
Optionally, you may select "Edit" to open the "Recognize Text - Settings" window to change your preferences.
