Logo
Versions
| Version | When to use |
|---|
| Primary (stacked) | Default. Icon above wordmark on white. |
| Landscape | When height is limited. Icon to the left of the wordmark. |
| ‘Metadata from Crossref’ | To indicate that metadata has been sourced from Crossref. |
All logo files are at assets.crossref.org. Reference them directly rather than downloading, so your site picks up any future updates automatically. Contact our community team for variations or special use requests.

Reversed logo (white on dark)
Use on dark or richly coloured backgrounds where the colour logo would clash. This file is not on the CDN — contact the community team to request it.
Icon only
For contexts where the wordmark is not needed (favicons, avatars). Use sparingly. Contact the community team to request this file.
Use this if you display metadata sourced from Crossref.

Logo do nots
- Do not alter proportions, rotate, or recolour the logo
- Do not reposition the icon relative to the wordmark, or use the wordmark alone
- Do not place the logo over photographs or complex backgrounds
- Do not add text, labels, or effects to the logo
- Do not create your own brand extensions using the Crossref icon
- Do not write “CrossRef”—the lowercase ‘r’ is intentional
Displaying Crossref DOIs
Crossref DOIs are persistent links and must be displayed as full HTTPS links in reference lists and anywhere they appear.
Correct: https://doi-org.turing.library.northwestern.edu/10.XXXX/XXXXXX
Incorrect: doi:10.XXXX/XXXXXX
You can optionally prepend the Crossref icon to the link:
https://doi-org.turing.library.northwestern.edu/10.13003/5jchdy
See the official Crossref display guidelines for full details. Displaying DOIs as full HTTPS links (and following the full display guidelines) is an obligation of Crossref membership.
