Begin by going to the Databases tab on the library home page and choosing a database in the alphabetical list. I've listed some recommended databases here.
If you find that the article you are looking for is not available online, don't be too concerned. Not everything is available electronically. With the title, issue number, year, and page numbers in hand, check out the UNT Library Catalog. Do a journal title search and check to see if our library holds a print copy. If not, you can put in a request from another library using our Interlibrary Loan Service.
UNT's Libraries provide access to thousands of journals. Below are only a small number of the journal titles offered relating to Library and Information Sciences.
