Work Types Overview

Work types classify the form of a scholarly document. Each work has exactly one type. Use these values with the type filter: filter=type:article.

Full definitions of each type and how OpenAlex assigns them are in Work types.

Values

preprint An article whose primary location is a preprint server
reference-entry An encyclopedia, dictionary, or handbook entry

The display name for each type is the same as its ID.

Note: book-review, conference-abstract, conference-paper, data-paper, and software-paper are newly added to the vocabulary. They are being rolled out, so coverage is currently low or zero and they may not yet appear under works?group_by=type.

Warning: The boolean field is_paratext is deprecated — it is now true exactly when type is paratext. Use filter=type:paratext instead of filter=is_paratext:true.
