User search‐limiting behavior in online catalogs: Comparing classic catalog use to search behavior in next‐generation catalogs

The purpose of this study is to show how the addition of a next‐generational overlay to an existing online catalog can lead to more‐refined searching by users. Users of classic online catalogs have always had the ability to refine their searches and define better the specific type of material they want. However, research in the last two decades has consistently shown that few users take advantage of this extra step. Now with the rise of discovery platforms like Encore and Aquabrowser, the limiting capabilities are automatically displayed to the user, and this study aims to demonstrate that this creates a significant change in search behaviors.

The library worked through months of its search logs for both the classic and online catalogs and compared data from the two platforms. Similar log data were obtained from other libraries to confirm that this was a universal trend.

The study shows that users are 15‐20 times more likely to refine their searches if they are searching in a discovery platform.

Librarians can base their bibliographic instruction sessions on a better understanding of the search behaviors likely in the two kinds of catalogs.
