We encourage publishers to provide as much relevant content as they comfortably can. The more high‑quality material we receive, the more accurately we can identify usage, match activity to your works, and ensure royalties flow to the right titles.  A sensible starting point is your most valuable or most frequently used titles. From there, we can expand together based on your priorities and the specific initiatives you opt in to. If you have the capacity, a continuous feed of new or updated content is ideal—it keeps the system current, improves matching rates over time, and ensures that emerging usage is captured rather than missed.  In short: the broader and more up‑to‑date your content supply, the stronger the evidence base and the greater the potential return. 
No, providing content to CLA does not mean your files are automatically made available to licensees. Supplying content is about improving identification, matching, and reporting, not about giving open access to your works.  How your content is used depends entirely on the specific initiative you opt in to: 
  • For usage‑tracking initiatives (e.g., school scanning integrations): your files are used behind the scenes to improve matching accuracy. They are not distributed to users. 
  • For Born Digital in HE: your content is only made available to students and staff at institutions that already hold a valid CLA Licence, and only through controlled, trackable links. 
  • For infringement detection (Reclaim): your files are used solely to help identify unauthorised copies online. 
In every case, you remain in control. We only use your content for the purposes you explicitly agree to, and always within a secure, rights‑respecting framework. 
On a UK-based encrypted CLA SFTP with access restrictions. Content is not read or consumed; storage is solely for permitted matching and tracking. 
You receive unique SFTP credentials and instructions; connect via your preferred client and upload content/metadata as per guidance. CLA stores content securely for matching and delivery within permitted initiatives. 
EPUB 2.x/3.x, web-ready PDFs (crop marks not removed), standard XML, and cover images (PNG, JPG, SVG). 
Supplying content increases visibility, improves attribution, and expands the pool of legitimate, licensable use. Those three factors together create the conditions that increase the chances for higher and more accurate collective licensing revenues.Â
