Alert services are a great way of keeping abreast of topics that interest you. Rather than searching the Web regularly to find new content about your areas of interest, an alert service keeps you informed by sending you notices when new material is added to the Web that matches your registered search criteria. Alert services are examples of push technology that delivers or pushes information on your desktop instead of your going to search for it. If you want to be on top of the web literature about a specific topic, an alert service is your way of doing so. Alert services are also useful for following news stories on a particular topic or for monitoring changes to a particular web site in which you have an interest. Alert services are especially helpful for teacher-librarians who want to stay current with developments in their profession and in the field of education. Whichever Google alert service you choose to use, you will find that the push technology behind the service will keep you better informed about the people and the events in your areas of interest. Alerts are a powerful tool in your searcher's toolkit. They deliver information tailored to your interests, and they deliver it regularly.
