There are three main ways to add works to your ORCID record:
Link your works from another system (recommended)
To link works from another system, choose Search & link from the Add menu in the works portion of your record.
Select a system from the list (CrossRef is a good general source, others will depend on your discipline). You'll be asked to authorize the system, and will then be able to identify works in that system that are yours and that you would like transferred to your record. Each system behaves a little differently, and there may be a couple of intermediate steps not described here. For more information, see Add works by direct import from other systems in the ORCID Knowledge Base.
To manually type in information about your works, choose Add manually from the Add works menu in the works portion of your record, and complete the form to describe a work. For more information, see Add works manually in the ORCID Knowledge Base.
