These are just a handful of the many databases available through the Texas Tech University Library. Your topics can be in education, social science, and science databases so I have listed the most important/comprehensive in each area. Also, the majority of these databases will allow you to format your citation in APA style and cut/paste into your wiki.
The TTU Libraries hold a number of print journals, which can also be found through the Library Catalog. In addition to print, patrons can access several E-Journals online.
The Library offers some trial databases that might assist you in your search for information. Please view these sources and fill out the evaluation survey link.
Hint: Limit to domains like gov,edu,mil,org.
