Read Together Diamond Bar 2025

Thank you to everyone who supported and participated in this year’s Read Together Diamond Bar that was held throughout the month of April. It was a joyous celebration of community and literacy. There were activities for all ages that brought people together around books and literacy. Special thanks to Mayor Chia Yu Teng and the entire Diamond Bar City Council for proclaiming April 2025 as Read Together Diamond Bar month. Also, special thanks to our Community Library Manager Cynthia Yu and her staff for providing such educational, innovative and fun activities throughout the month of April.

Four Seasons Book Group

The next book discussion will be on Saturday, August 9 at 11 AM in the Library Windmill Room. The book selection is Lovely One by U.S. Supreme Court Justice Ketanji Brown Jackson. Ms. Jackson, the first Black woman ever appointed to the Supreme Court of the United States, chronicles her life story and her extraordinary path to becoming a jurist on America’s highest court, in her inspiring, intimate memoir.

Refreshments will be served. You do not need to have read the book to participate–everyone is welcome. Come join us and bring a friend or two. Call 909- 576-8536 for more information.

Supporting Our Library in 2024

The Friends of the Library serve the Diamond Bar Library in many ways.  In addition to sponsoring the popular summer reading contest, there are many special programs throughout the year for children, teens, and adults. The classes include art with lessons on painting and mosaics, tie dye and punch needle, science workshops that feature STEAM, experiments on the solar eclipse, wildlife, marine biology, world music, glass workshop, ornament making, book discussions, fun cooking lessons, and story time for children.  Special guests are often invited to teach these lessons and share their unique skills and passion.  These are just some of the programs that the Friends supported last year.

The Friends enhanced some of the furniture in the teen area by re-upholstering and upgrading seating. By installing comfortable and functional furniture, readers can more fully enjoy reading and learning. In addition, the Friends supported our librarians with a special appreciation luncheon that shows how much we value their work in our community.

Our library is so much more than a place to check out a book or DVD, it is a place for learning and experiencing something new, and it can also be a place to connect with others. Providing these special programs and experiences is part of our mission to support libraries and literacy in the community.  To our supporters, thank you for your generous support, so that we can continue to accomplish our mission together.
