Our journal now offers three free and easy-to-use services designed to alert users as soon as new Web Edition content is published online. All methods ensure that you are alerted when new content that interests you becomes available.

Email Alert（以下简称EA）是目前流行的电子期刊派发方式，可根据EA订阅用户的需求自动地发送信息（如杂志的当前期目录、摘要等）。 目前我们已经开通免费Alert服务，订阅的用户可按自己的需求免费获取最新目录。

If you have multiple Email addresses, please repeat the subscription.
