Welcome, fellow number crunchers! You know what’s more fun than calculating the Return on Investment (ROI) of electronic resources? Literally anything else. But since we’re here, let’s make the most of it!
The basic formula for Electronic Resource ROI is:
ROI = (Gain from Investment - Cost of Investment) / Cost of Investment
