What happened to CLUES and the Discovery Search?

You clicked on a link to the CLUES Library Catalogue or the Discovery Search (Encore). Why isn't it working?

On July 15, 2020, the Concordia Library joined 17 other Quebec university libraries in migrating to a new shared catalogue: the Sofia Discovery tool.

The Library has officially retired the CLUES Library Catalogue, Discovery Search, and former E-Journals portal causing any links to these systems to break. We have done our best to update links on our websites, but it is inevitable that some old links remain. We apologize for the inconvenience this may cause.

Depending on the type of link you have, there are some options:

If your CLUES or Encore links looks like one of the following:


You can search for the "b" number in Sofia, which in this case is a keyword search for "b3840850?". Please include the question mark on the end for best results. If this search returns more than one result, please select your result according to title.

In the case of links to e-books, it is possible that a search for a "b" number will not return any results. Please search by keyword or title.

If the link contains search terms

If your link is not to specific record, but includes search terms, please search for the same terms in the Sofia Discovery tool.

Special Collections links

If your link is to a special collection, you will find new links on the Special Collections - Book Collections section of the website.

Where do I go for the E-Journals Portal?

E-Journals are also in the Sofia Discovery tool and can be found at or from the E-Journals link in the Library Links dropdown menu in the top right corner of the search interface. From the Journals section it is possible to search by journal title and ISSN like in the previous E-Journals Portal, and you can search by DOI (Digital Object Identifier) or PMID (PubMed Identifier) from the Articles section. Please be sure to select the appropriate Identifier before launching your search.

Browsing for journals or subscribed packages is possible by title, however browsing journals by subject is best done using a subject search in the Advanced Search section of the Sofia Discovery tool.
