Most research starts at ONU with the search box on the library's homepage, which utilizes the SeachONU database. SearchONU is a great place to start out and test your topic. It searches the majority of the library's 200+ databases, as well as its ejournals, ebooks, the library catalog, and the OhioLINK catalog.
For topics that need more specialized databases than SearchONU, or are outside the general scope of databases listed on a research guide for a course and include elements that might be part of a different discipline's subject-specific databases, make sure to check out the library's A-Z list of databases. A button titled "Databases" is right under the main SearchONU box on the library's homepage, and it will take you to this list.
For topics that include elements that are part of various discipline's subject-specific databases, or to search across all of the subject-specific databases for a particular subject (example: there are multiple education databases and multiple environmental databases), databases that use the same platform allow users to create custom databases combinations to fit their specific needs. Most of Heterick's databases use the EBSCO platform, so most of them can be combined for a search that is broader than a single database but not as broad as SearchONU.
Each of these searches may benefit from combining subject databases across multiple disciplines. In example one, you'd probably have luck finding information on this topic in both education AND psychology databases. In example two, you may want to search across the business and management databases, as well as the education databases.
