First off, there is no set percentage of copyrighted material that may be copied by another not having permission from the copyright owner. In determining whether the "doctrine of fair use" applies to your use of these articles, a court looks at what the copyrighted work is, why you're using it (i.e. Is it commercial or non-commercial), how much you use, and any effect your use has on the market for the copyrighted work. Some examples of fair use include quoting excerpts for illustration, clarification, and criticism. In this instance, more specifics that address the concerns mentioned above are necessary to better answer your question. Please contact an attorney with these specifics before continuing your use of copyrighted material.
