Primo Central is a search engine that provides credible, relevance ranked results from the Library’s online and print collections in a single search.
It includes everything found in the Library’s catalogue, plus a lot of the content available through the Library's databases.
Try searching in Primo Central when you might otherwise search Google Scholar, Primo, ScholarsPortal, or a research database like JSTOR. Primo Central is not intended to entirely replace these other search tools, but we hope that it will be a much-valued addition to your research toolkit.
Primo Central includes hundreds of millions of records for books, journal articles, e-books and e-journals, news articles, and much more. It includes everything found in Primo / TRELLIS, plus information usually found in research databases.
Primo Central may include some or all of the databases and journals that you already use. Some databases and journals allow full-text searching, others include only citation information (e.g., title, author, abstract, etc.), but may be accessible from Primo Central via SFX links.
Primo Central includes everything that is in Primo/TRELLIS, plus hundreds of millions of scholarly articles and online records.
The search engine that supported the Journal Articles Quick Search is being phased out. We hope Primo Central will provide a faster and more comprehensive search alternative to the Journal Articles quick search.
Our Primo Central trial will start in the summer and run through the fall term.
Our users have told us that they want a way to search all of our resources simultaneously. Right now, web-scale indexes like Primo Central are the closest thing to making this possible. Our participation in this trial will give us an indication of how well this type of web-scale index meets your search needs.
Most subjects are covered, but the Library’s Subject Guides also offer recommendations for the best resources for each uWaterloo academic department.

Primo Central's vendor, ExLibris, works directly with publishers to obtain permissions to index specific journals, newspapers and other serials. Publication data can come from any number of places: direct from the publisher, or from an intermediate database.
For this reason, we don’t know exactly what the overlap is between Primo Central’s content and the content found in specialized research databases. In some cases it might be close to 100%, in others, 50-75%.
Primo Central and Google Scholar are both search engines that let you quickly search across a massive index of scholarly information.
Primo Central and Google Scholar search different bodies of scholarly content. There is overlap, but there is content findable in Primo Central but not Google Scholar, and vice-versa. The two search engines perform relevance ranking in very different ways.
Primo Central's sophisticated relevance ranking algorithm is a 'trade secret' of the software developers at ExLibris, so we are unable to explain exactly how it works. However, it usually gives priority to "exact title" matches on your search keywords.
For instance: a search for "practical grammar" will return items with the exact title "practical grammar" at the top. A search for "the practical grammar" will return almost identical results, but with priority given to titles with "the" in them.
Facets appear on the left-hand side of the search results screen and can help you to refine your search results.
By clicking on any of the facet values you can limit your search results to only results with these values.
Facets are dynamically generated from the top 200 relevant results. The number for each value is taken from the full set of results.
This is an example of facets:
Primo Central includes article citation information as well as full-text information. It may be that the search term is matching somewhere in the full-text.
When switching between tabs only the search terms stay. The drop down selections available in the "Books and more" and "Articles and more" tabs don’t carry over.
Primo Central uses a list of peer-reviewed journals supplied by SFX (GetIt@Waterloo) to determine what is peer-reviewed.
The Primo Central software is relatively new and is expected to change and improve as new features are implemented and new content is added.
Primo Central is an example of “software as a service.” The Library has a license with the vendor ExLibris to provide Primo Central for the Library’s collection. In this sense, it is more similar to the Library’s various article databases (e.g. Web of Science) than it is to the Library’s Catalogue system (a locally-hosted software system that experiences major but infrequent upgrades).
