When a database includes full text for an article, the results list and detailed record will have links for PDF Full Text, HTML Full Text, or Linked Full Text. Follow those links until the article is displayed.
If no such links are provided, look for a Find It @ UHCL link, which can lead to full text from another source.
If you don't find an article online, submit an article request to obtain the article through the library's ILLiad Interlibrary Loan service.
