About Us
Hi there! I’m Collette Jakubowicz, and I’m the owner and co-founder of Librarians Teach, as well as the library curriculum author behind Mrs. J in the Library.
I’m a certified teacher-librarian with over 18 years of experience working in school libraries and directly with teacher-librarians and library media specialists.
I know that you’re a busy school librarian with too many demands on your time and energy. Librarians Teach was created to make your job easier.
The Librarians Teach marketplace offers downloadable lessons, bulletin boards, and resources to purchase, as well as online professional development courses.

How we can help you
- We curate engaging, high-quality resources that are created by experienced school librarians, just for school librarians and library media specialists. No more scouring through an entire K-12 market when you just want a library lesson or new shelf signs.
- Our library lessons are aligned to the AASL National School Library Standards for Learners and national Common Core Standards. Over 90% of our lessons have a full, complete lesson plan as well (and we’ll clearly tell you if it doesn’t).
- Our lessons and resources are designed to work with any class schedule (fixed, flexible, or combo), and with or without a library assistant or clerk.
- We make it easy for your school or district to order resources with a purchase order (just like they do for other teachers).
- For school purchase orders, we offer one-on-one consults and customized packages to meet your school library’s needs. You get just what you need and nothing you don’t.

Our Founders and History
Librarians Teach was founded in 2019 by Collette Jakubowicz and Cari White, two certified teacher-librarians with over 30 years of combined experience teaching in elementary school libraries.
During and beyond the pandemic, they worked full-time as school librarians while supporting customers with online/hybrid library curriculum and live, virtual professional development.


2023
Exhibited and presented at the 2023 AASL National Conference in Tampa, Florida.
We were joined by Leigh Collazo (middle) from Mrs. ReaderPants, one of our curriculum partners.
At the end of 2023, Cari retired, and Collette took over as full-time owner.

Land acknowledgement:
Librarians Teach LLC is a business located in Lancaster County, Pennsylvania.
As I live, work, and tend my garden on this land, I acknowledge that I am on the ancestral lands of the Susquehannock and Lenapehoking (Lenni-Lenape) peoples. My commitment to grow some of my own food, avoid pesticides, and let rainwater nourish the soil is a small but meaningful way to honor their enduring legacy of stewardship.
I recognize that my actions to care for this place are part of a continuous relationship with these lands and waters, and I strive to walk with respect and gratitude for the sustenance they provide.
