What we do

An unparalleled platform providing independent reading and information services to K-12 professionals and library leaders in the US

Collectively, and individually, our businesses help librarians and teachers build an appetite for lifelong learning and serve the needs of their communities, and help publishers and other companies achieve their marketing and business goals within the education ecosystem.

We bring the best of children’s literature, curated by age, reading level and genre, and reading programs into the hands of librarians and teachers, and through them, to students across the country, to build a passion for reading at the earliest ages.

We strengthen the value provision of all constituents in the library and K12 ecosystem through data, reach, insights, thought leadership, relationships, access, and community engagement, in order to further their mission of building literacy, learning, student success, and services to their communities.

“You are a wonderful company and I enjoy doing business with you. Your selections are always top notch and those that are the most anticipated. I love the fact that I get to have JLG selections all year, even when my budget is frozen or to lean for purchasing new books. Keeps my collection looking new and relevant.”



“I love Junior Library Guild for so many reasons. First and foremost, my students love them and recognize the shipping box! When they see it sitting in the circulation desk, they always want to know what books came and ask if they can be the first to read the new books.”



“LJ provides connections between our profession and industries, legislation, and other issues that affect or influence what we do and how we do it. LJ's professional development offerings are professionally presented and reasonably priced.”



“I feel confidant buying books recommended by Horn Book staff and its contributors whom I believe share the same desire to get the best books in into the hands and minds of our students.”



“I told my upper graders the secret of the little gold sticker (JLG sticker) in the front of the fiction books. After I told them that these were specially selected by experts to be good books, they were going through all of the books looking for the stickers.”



“I like the SLJ reviews because they are written by practitioners in the field who know first-hand where books will fill niches in collections.”


New Hampshire

“I depend on JLG and look forward to receiving books each month that I know will be popular with our students and will keep our collection up to date with quality titles. Customer service has always been excellent also.”



“The Horn Book reviewers have discerning taste which I value in making book selections for my library.”



“I love the (JLG) backlist! There are many titles that I have been able to acquire multiple copies of for Battle of the Books and Volunteer State Book Award reading lists.”



“LJ offers an extensive, diverse array of channels and information for library employees in many areas of the profession.”



“SLJ is the place I go to first when it comes to book recommendations.”


New York

“[LJ] combines both news and resource reviews - giving me a big picture beyond headlines. It provides cutting edge resources - but scales them to a realistic level that can be replicated.”



“SLJ topics & articles present the latest information on books & authors.”

Mary Beth


“[LJ] has a long history of covering all of librarianship as a profession, which helps me understand where my library colleagues are in their various libraries.  Its newsletters are superb and well-focused.”



“LJ is a well-respected journal with outstanding editors and authors with extremely useful and relevant articles.”



“[The Horn Book] is the BEST guide to children's literature, period.  I love all the features, and I'm always sorry when I finish reading it!!”
