Joni Cassidy

President & CEO

Joni co-founded CCS in 1985


Joni started her library career at 16 years old as a Library Page in her local public library where her responsibilities increased as her education advanced through an AAS degree in Business to a BA in Arts to an MLS at the Palmer School of Long Island University.  Her first professional position was setting up a federally funded Job Information Center for Eastern Long Island. Later she worked as a young adult services/audio-visual librarian, academic librarian, and Head of Public Services before starting Cassidy Cataloguing Services in 1985. 

Her company creates original MARC records for electronic resources of legal, scientific, corporate, and other publishers, creates publisher cataloging-in-publication for hundreds of small publishers and self-publishing authors, and provides contract cataloging services to law libraries throughout the U.S.  In the day-to-day scheme of things, Joni is responsible for overseeing all the active projects, supervising the staff, negotiating new contracts, and working with new customers to get their ventures started.

Joni has served as Adjunct Professor at four library and information science schools in the New York/New Jersey metropolitan area teaching the core technical services course, advanced cataloging, and cataloging for school media specialists.  She is most proud of the students who have entered her classes expecting to suffer through it, and have left as Catalogers!


Michael Cassidy

Vice President & CFO

Michael co-founded CCS in 1985


Setting an example for Bill Gates, Mark Zuckerberg, and Kim Kardashian, Michael never finished college but went on to do great things in the theatrical lighting industry.


After tiring of watching Joni using a memory typewriter to make catalog cards, he bought her an IBM compatible PC, with two floppy drives, because the IBM XT hadn’t been invented yet.  Before long he found himself helping to run Joni’s company, preferring it to a future of short-term theater gigs.


Michael designs data projects, solves technical support issues, runs accounts payable and receivable, and is responsible for all the technology in the office.  What is left of Michael’s hair is grey.


Keelan Weber

Head of Technical Services

Keelan has been with CCS since 2023


Prior to joining Cassidy Cataloguing, Keelan worked as Head of Cataloging and Resource Management for an academic law library managing the library's physical and electronic collections, troubleshooting e-resource access issues, and guest lecturing on library methods for legal research. 

Keelan received her BA in French Literature and Language and her MLIS from the University of Western Ontario in Canada.


She has a fascination for plant patents and she is perpetually asking "what's for dessert?"


Megan Staloff

Client Relations Specialist

Megan has been with CCS since 2007


Megan has been with Cassidy Cataloguing since 2007 and has worked under a variety of different hats until settling into her current position of Client Relations Specialist. She handles the day-to-day operations of the office and client accounts. She not only interacts one-on-one with the clients and prospects, but responds to inquiries for services, organizes and oversees project execution, client management and accounts receivable.

In exchange for biscuits and the right to lay on Joni’s fainting couch, Megan’s dog, Cinch, protects the staff from all manner of delivery men: FedEx, UPS, and that burly water delivery guy!

Megan holds a BS degree in Equine Studies with a concentration in Business Management from Centenary University. Most days, she would rather be riding her horse to work.
