Direct is a free service that delivers electronically the table of contents of Elsevier journals and books. Imprints covered are Elsevier, Pergamon, North Holland and Excerpta Medica. Digests are available for specific subject categories. This is a very comprehensive service with many different options available. There is a charge for the service.
Several options are available.
A user may set up as many as five different alerts at any one time. For journals outside the library's subscription or licensing agreement only tables of contents and abstracts will be received. The saved search can be executed as the system is updated, traditionally each weekend from January through October and once monthly in November and December. Alerts can be sent either daily or weekly, and up to 10 searches may be stored at one time. The Library must subscribe to the print in order to have access to the fulltext electronic version of an article.
