CLSI’s Digital Rights Management Policy

CLSI has implemented watermarking of documents to help protect the intellectual property of its standards and guidelines.

The importance of protecting copyrighted materials distributed through the Internet is a major issue for organizations today. Our volunteers and authors contribute tremendous amounts of time and expertise in developing our standards and guidelines. Sales of these documents are a major source of revenue for CLSI. The unauthorized distribution of these documents interferes with our ability to sell copies of the documents in support of our non-profit mission.

To prevent unauthorized distribution or replication of our proprietary documents, we have added a watermark to our electronic documents. The watermark will display red text using variable information along the bottom of every page of a document as follows:

The first line displays:

“Licensed to: Full Name. Single User License only.”

The second line displays:

“This document is protected by copyright. CLSI order # 99999, id # 999999, downloaded on day month year.”


A watermark also will appear on our inventory of ISO documents to comply with ISO’s policy for resellers.

If you have any questions or comments regarding watermarking, please feel free to contact us at customerservice@clsi.org.
