Just a quick computing tip today. If you want to get an accurate snapshot of what is appearing on your computer monitor at any given time, then just press the 'Print Screen' button (it's usually towards the top-right corner) on your keyboard, then open the document where you want the image to appear, right-click your mouse and select 'paste' from the menu. Voila! Your screenshot should now appear, and you will be able to resize it, move it around, or cut it down to size for your requirements.
This tip may be useful if you need to drop a screenshot into an essay to demonstrate a point that you are making. Also, if you are having difficulties with your searching from your home computer, then sending a screenshot to myself or one of the other subject librarians is often useful in helping us to diagnose what the problem may be.
