It is important to keep your references up-to-date and there are several ways to achieve this.  In the section protocol driven search you learnt how to save searches.  Each database may be different but the concept is the same:

• Look for a link to ‘My profile’ or ‘Saved searches’

• Set up a profile with your email address

• Run your search

• Save your search as an alert

Zetoc Alert is a service that sends you email alerts when new data is loaded into the database (it is updated daily so this can be as soon as 72 hrs after publication).  Instructions can be found on the website.

For books, individual publishers, as well as websites like Amazon, offer email alerting services.

You can search for the latest working papers at the Social Science Research Network (SSRN).
