R-Search is the library's search service that allows you to search almost all of the library's resources simultaneously. The system allows you to search for print items (like books and DVDs) and online items (such as articles and streaming video).
Rollins users have additional features available to them. If you log into your account you can see when your checked out items are due and renew them, and you can save articles to read later.
You might have used a similar system like this at another library and heard it referred to as a "catalog." R-Search uses the Primo interface and the records in it come from a system called Alma, both of which are made by ExLibris, a ProQuest company.
You can get to R-Search by opening any browser and going to https://primo.rollins.edu/.
In most cases any of these routes will search the same catalog of items, so use whichever is most convenient for you.
