Most of us know the important journals likely to publish valuable research. Virtually all these journals will provide table of contents as direct email alerts to you.
Create your own account or register at the journal website to activate these personalised options. Alerts are added to your personal profile and are usually described as Alert me about new Journal Issues or Set e-mail alert
For large journal collections such as ScienceDirect and Nature and databases such as MEDLINE, you can create multiple alerts and search profiles and these services will push updates to you by email.
