How to Use Primo - The CT State Library Discovery Tool

What is Primo?

Primo, Library Catalog

What is Primo?

Primo is the discovery tool at the CT State Library - our library catalog. It includes print, electronic, and digital resources at the Hartford location, as well as resources at the Middletown Service Center and the Connecticut Library for Accessible Books (CT LAB) (formerly the Library for the Blind and Physically Handicapped, LBPH). Primo is a one-stop location to search for books, articles, and more! 

Search as a Guest

If you do not have a library card, you can search Primo as a guest. When searching as a guest, you will not see the circulation rules for items held at the library. Please contact us to inquire about the availability of our materials. 

What is in Primo? What is not?

This is a little tricky - it depends on how you choose to search.

  • CT State Library (CSL) - we have the search tool set to CT State Library (CSL) library catalog when you first open up Primo from our web site. This setting searches what is traditionally found in a library catalog: our books, government publications, titles of journals and newspapers (but not the articles), maps, some of our database content (requires CSL library card to access) - in many formats (online, in print, microforms, etc.).
  • CSL Catalog, Plus Articles - this searches our catalog (like above) plus many articles from a collection set by Primo. Some are freely available, some require our library card, and a few might not be available. For those not available, you can bring the citation information to your local library and ask them to help you. CT State Agencies should contact us. We have additional databases available on our A-Z Databases page. 
  • Middletown Service Center - this option is for libraries in Connecticut. Materials are available only for CT libraries. Please contact them with questions.
  • CSCU Library Consortium - searches across all catalogs of Connecticut State Colleges & Universities (CSCU) Library Consortium, consisting of Connecticut’s 12 community colleges, four state universities, Charter Oak State College, and the Connecticut State Library.

What happened to CONSULS, the old catalog?

CONSULS was replaced by Primo on March 30, 2017. Primo allows you to search all institutions in the CSCU Library Consortium. However, you can limit your search to the CT State Library. For a search experience that is similar to using a card catalog, please see the Browse Search tab. 

Select CSL Catalog from the search bar drop down menu to search the electronic and print holdings of the State Library (including the Middletown Service Center and LBPH). 

search box set for CSL catalog searching only


If you wish to search beyond the CSL Catalog, you can select other options in the search box drop down menu. Please note that some resources may only be available within the library that owns or subscribes to them. 

CSL Catalog - Searches electronic, print, and digital resources available through the CT State Library. Primo Central - Searches CSL subscription databases, plus selected freely available resources. LBPH Large Print - Searches the collection of the Library for the Blind and Physically Handicapped. Middletown Library Service Center - Searches the collection of the Division of Library Development. CSCU Library Consortium - Searches the library collections of Connecticut's 4 state universities, 12 community colleges, and the CT State Library.
