Annotation is the process of assigning GO terms to gene products. The annotation data in the GO database is contributed by members of the GO Consortium, and the Consortium is continuously encouraging new groups to start contributing their annotations. The list of links below offer details on the GO annotation policies and the annotation process, as well as direct users to other pages of interest on GO annotation conventions, the standard operating procedures used by some consortium members, and the GO annotation file format guide.

- Guide to Evidence Codes: Explanation of the codes that are used to indicate the nature of the evidence that supports a particular annotation.
- Annotation Conventions: guidelines which apply to all annotation methods and are particularly useful for manual literature-based annotation
