Programs & Events


What is KinderGO?

KinderGo is a program designed to enhance educational awareness through city-wide library card distribution to Ontario’s kindergarten students. This program gives kindergarten students and families a personal invite to the library to ensure they are introduced to the services offered to them at the start of their child’s educational experience.

Who does it serve?

KinderGO serves Kindergarten aged students and families. During KinderGO, city staff visit classrooms to share a fun read-aloud story and provide students with a KinderGO bag, wallet and library card. 


Ontario City library staff, as well as other departmental staff, visit each kindergarten classroom in the City of Ontario. Visits are coordinated within 4 different districts in the city: Ontario Montclair School District, Mountain View School District, Cucamonga School District, and Chino Valley Unified School District.

KingerGo in 2020 - 2021

The kindergarten class of 2020 -2021 is invited to participate in KinderGo by visiting their local Ontario City Library location to register for a KinderGo library card.

Some of these collections include Armstrong Nurseries, General Electric Ontario Hotpoint Works, Ontario Motor Speedway, and more. Browse the finding aids below. You can visit us to view the collections, but we need to know ahead of time what you want to see. Give us a call or send us an email at least one day in advance: (909) 395-2206 or [email protected].

Ontario Reads

Ontario Reads 2021

Patterned after the American Library Association's One Book, One Community initiative, Ontario Reads is an annual opportunity for the library to connect to the community through literacy by selecting one book for participants to read, share and discuss. Selected titles are complemented with informative and creative programming that may include arts and crafts, films, guest speakers and sometimes meet-and-greets with the author.

For 2021, Ontario Reads is part of the Book to Action: Health Initiative, focused on mental health and the ways that mental health and physical health are connected. Book to action is a grant backed by the California State Library and California Center for the Book. The chosen title is Maybe You Should Talk to Someone by Lori Gottlieb, and the community partner is the Ontario-Montclair School District's Family Resource Center.

Ontario Reads Launches May 3, 2021 by offering free copies of Maybe You Should Talk to Someone at both Ontario City Library locations (Limit one per household). Participants are invited to join the kickoff event, where we host a live Zoom discussion with the author, Lori Gottlieb on May 26, 2021 at 6 pm to hear the author speak about the book, her take on mental health and allow participants to ask her questions.
