Crossref DOI report for Khulisa Journals 23 July 2025

[Ina Smith]

Dear Khulisa Journal Editors/Journal Managers,

The resolution report from Crossref is a monthly statistical summary that shows how often DOIs registered by a specific prefix (e.g. 10.17159 for ASSAf) were accessed, or "resolved", via the DOI system. Also how many failures there were.

Maybe of interest for you - also for inclusion in your reporting. I will try to - going forward - provide you with a summary every time. Items in Bold refer to Khulisa Journals.
