There are several places you can add a ProQuest Search Widget to your site to make it easier for your patrons to quickly and easily search your collections through ProQuest.

Create a ProQuest Search Widget limited to the appropriate databases for the subject page. Add any appropriate search criteria (such as limiting searches to full text documents or to scholarly journals), then add the Search Widget to your subject page.
Example Library Subject Page

Create a ProQuest Search Widget limited to the appropriate databases for the current issues and add it to your Current Topics page.
Example Topics Library Page

Create a ProQuest Search Widget for discipline-specific searches, limiting databases and pre-populating search terms (such as nano science) for different College Department pages.
Example College Department Web Page

Create a ProQuest Search Widget limited by database and/or search criteria for individual course subjects and add it to individual course pages.

And don't forget a ProQuest Search Widget for quick searches on the library home page!
