Classic Catalog vs. Discovery Layer (Encore Duet)

Which platform should you search? It depends on your needs. This guide will highlight the differences between the traditional "Classic Catalog" and the discovery layer.

When should I use this platform?

Classic Catalog - To determine if the University Libraries has a copy of a specific book/movie/score or subscribes to a specific journal.

Discovery Layer (Encore Duet / Quicksearch) - To discover articles, eBooks and other content on a given topic.

How does it work?

Classic Catalog - Search by keyword or using author, title, subject, call number, and other indexes. Keyword searches relevancy ranked, index results presented alphabetically or in numerical order.  Use the Advanced Search option to limit your results by format type, language, specific library, and more.

Discovery Layer (Encore Duet / Quicksearch) - All searches are keyword-driven and all results relevancy ranked. Use the Advanced Search option to limit by format type, language, specific library, and more.  You can also limit results by clicking on facets (location, publication date, format, etc.) after searching.

What is included in the search?

Classic Catalog - Items held by University Libraries and partner schools, either in print copies or through electronic/digital access.  

Discovery Layer (Encore Duet / Quicksearch) - In addition to the physical items held by University Libraries and partner schools, the discovery layer also provides access to articles and other online resources.

Does the platform search journal articles?

Classic Catalog - No. Searches books, audiovisual materials, sound recordings, and many other formats, but does not search for articles within journals. You can use "Journal Titles" to identify if the library subscribes to a particular journal.

Discovery Layer (Encore Duet / Quicksearch) - Yes. Searches for articles within most University Library subscription databases and articles and e-resources from the EBSCO index. When the article full-text isn't immediately available, "Full text finder" links help you track down full-text.

What are the differences in the search results?

Classic Catalog - Keyword searches are ranked by relevancy, but title/author/subject and numerical searches are presented in alphabetical or numerical order. Searches will yield fewer results in Classic Catalog than in the discovery layer.

Discovery Layer (Encore Duet / Quicksearch) - Results are presented according to EBSCO's relevancy ranking algorithm. You may be overwhelmed at the huge amount of results you find in this platform.  If so, apply the facets to refine your results.

 

Can I search for non-UofM materials?

Classic Catalog - Unless you limit your search to only retrieve UL materials, you will find materials at our partner schools (JSCC, LeMoyne-Owen, and the Law School).  You will have to request these via Interlibrary loan.

Discovery Layer (Encore Duet / Quicksearch) - Unless you limit your search to only retrieve UL materials, you will find materials at our partner schools (JSCC, LeMoyne-Owen, and the Law School).  Additionally, you will discover articles to which UL does not have immediate access. Embedded "Request through Interlibrary loan" links facilitate requesting these materials.
