User needs. How much will our researchers appreciate the ability to start an ILL directly from the Primo interface?
Common use scenarios. How do our researchers use WorldCat searching, and how well are they supported by including a separate WorldCat scope or including WorldCat records in a blended search?
Example scenario: WorldCat (on campuses that do not use WC Discovery) is used frequently by more advanced researchers looking for a known item that’s not available on their campus. So, for example, a search for older, more unique monographs.
Quality of WorldCat-only search . Primo’s search functions for WorldCat data are significantly worse than WorldCat for precision searches. (Other libraries, e.g. Northwestern, have handled this by providing a link to WorldCat instead of using Primo.)
No facets display in Primo.
No fielded searches in Primo, e.g. in WorldCat you can search ti:[title term] au:[author name] .(but Advanced Search does work with the WC search profile)
Quality of blended search. How well does it work?
Results are worse with WorldCat. ExLibris strongly discourages using WorldCat records in default search. Default search ends up the most-used search, and including WorldCat records sort of breaks the facet display because it hides number of results in the facets.
(From experience, the format of a highlighted “Note” field in Ex Libris documentation is deceptive. It looks mild, with subtle yellow highlighting, but in reality it means ALARM.)“It is not recommended to blend third-party indexes with local and Primo Central searches in the library's default scope since this may impact the end users experience in the areas of facets and relevancy between the different indexes.“ https://knowledge.exlibrisgroup.com/Primo/Product_Documentation/020Primo_VE/Primo_VE_(English)/040Search_Configurations/010Configuring_Search_Profiles_for_Primo_VE
Examples of high-quality results are pending. Example: search for known title 1951 book “Argyll in the Forty-Five” in the U. Buffalo Primo scope should pull up a WorldCat record. But it doesn’t seem to. (WorldCat record docIDs start with “WorldCat.”) https://search.lib.buffalo.edu/discovery/search?query=any,contains,argyll in the forty-five&tab=UBSUNYPLUS&search_scope=UBSUNYPLUS&vid=01SUNY_BUF:everything&offset=0
