The full field information of a literature is important. But often, there are some missing fields when importing a literature from a webpage. It is time-consuming to add literature information mannually. Instead, adding field content automatically through DOI is efficient.

Specially, the button near doi may be changed from "View online" to "Lookup" literature information. After click this button, literature information can be retrieved from doi.org.

This feature is easy to complete since Zotero has the feature "Add by identifier", which adds a literature based on a doi prescribed by the user.
