This guide includes instructions for using ASU Library One Search.

What is One Search?

Why is there a separate Ebsco search scope?

For search results beyond the "ASU Library Catalog," the Library One Search uses a centralized index that encompasses hundreds of millions of records of global or regional significance that are harvested from primary and secondary publishers and aggregators. The number of records is constantly growing as additional data sources are added.

EBSCO does not send their metadata to be included in this central index. Instead, they require the system to do a separate call to their API (Application Programming Interface). Bringing these results back to the Library One Search and attempting to “blend” them in with the rest of the results from the central index causes significant issues with the accuracy of facet counts, relevancy ranking, and various browser timeout errors. Because of this, ASU Library has chosen to provide a separate search for EBSCO content.

Some EBSCO content is already available through our existing “All Resources” search. Common citations (for example, from Gale) may surface EBSCO full text in Primo. 

The ASU Library acknowledges the twenty-three Native Nations that have inhabited this land for centuries. Arizona State University's four campuses are located in the Salt River Valley on ancestral territories of Indigenous peoples, including the Akimel O’odham (Pima) and Pee Posh (Maricopa) Indian Communities, whose care and keeping of these lands allows us to be here today. ASU Library acknowledges the sovereignty of these nations and seeks to foster an environment of success and possibility for Native American students and patrons. We are advocates for the incorporation of Indigenous knowledge systems and research methodologies within contemporary library practice. ASU Library welcomes members of the Akimel O’odham and Pee Posh, and all Native nations to the Library.
