Google Scholar allows you to set up automatic email alerts, which will send you an email any time a new article is found by Google Scholar that meets the given search criteria. For example, if you are researching obstructive sleep apnea and headache, you could set up an email alert like this:
1) Perform a search in Google Scholar as you normally would. On your results page, click the Create email alert link at the top.
2) Enter your email address, specify how many results you want at a time, and click Create alert.
3) You'll then see a message like this. You will need to check your email and click the confirmation link to complete the email alert set-up process.
Note: When Google Scholar emails you a list of new articles, that list will not include Find It @ UAB Lister Hill links which take you to full text available through Lister Hill. Therefore, if you wish to try to retrieve the full text of an item in your email alert, you can go to Google Scholar directly, do a title search for the article (i.e., put the title in quotes), and make sure that your Scholar Preferences are set to show the Find It @ UAB Lister Hill links.
