If you have been unable to obtain certain journal articles through the Walden databases, Document Delivery Service or local libraries an easy and efficient service to consider is ordering from a commercial document service. Here are some of the reputable companies that provide document services.

Fees can range from $1.00 to over $100.00 (U.S. dollars). We suggest you compare prices among the services.

• Infotrieve is a research and document company that can provide full-text articles from over 150,000 journals. You can submit requests for citations you already have or use one of their search services such as ArticleFinder or eContent.
