Careful proofreading is the courtesy we pay our readers.

Here is a trick to help you proofread better:

• Take a post-it or index card. Fold in half, and  on the fold cut a rectangle 1 inch by 1/4 inch.
• Open up, and use this rectangle to help you proofread.
• Continuity keeps us from proofreading well.  We know what should come next, so that is what we see, instead of what is really there.
• When you drag your post-it with the rectangle across your paper, you break continuity.
• Once you have broken continuity, you will see typos, missing words, etc. that you missed before.

Your readers will thank you!
