In some cases, you may want to obtain copies of articles that are not freely available. In these cases you typically have several options.

1. Conduct an advanced search on the Internet. By entering the full title of the paper in quotes ("_") into an Internet search engine, you may be able to find a copy of the article if the authors have posted it. Also, try searching OAIster in case the paper has been deposited with a university archive.
2. Request a copy through your local public or school library. This is usually referred to as "interlibrary loan" or "document delivery" and is often a free service. Talk to your librarian for details.
3. Purchase and download the article. Most commercial publishers allow you to purchase and download articles individually. Cost varies by publisher, but expect to pay about $30 per article.
