I purchase almost all of our books from @MackinLibrary. They include free cataloging/processing. The only thing I need to do when I receive the MARC records is add sublocations. Theirs have everything else. I'm on a fixed schedule without any library admin time.

I hadn’t even gotten these out of the box before a student claimed checkout on them today. Thankfully @MackinLibrary had them shelf ready #bookposse @Jarrett_Lerner pic.twitter.com/fOuepj0WjF

I haven't had the pleasure of meeting Randal personally, but Kitty Heise is such a warm, wonderful person! She was so effusive about the book talks presentation I shared at the @MackinLibrary booth Friday morning. She seems like a great person to work for!

The new library was missing a few essentials (graphic novels especially). These just came in from my first @MackinLibrary order & will be out next week for circulation. I’m hoping to hear screams of comic joy when the students see… pic.twitter.com/e0vUR3U9RA

“The King County Library System has worked with Mackin Educational Services for over fifteen years to purchase and process collection material, primarily focused on early and juvenile reading level collection material. We are in the process of setting up the capacity for Electronic Data Interchange for order submission and invoice processing to aid the high volume of material we receive from them annually.
The staff and customer service representatives build long-term relationships with their customers and work proactively to ensure high levels of customer service. Our staff relies on Mackin for both excellent customer service and reliable products. Their staff respond quickly when we reach out with questions about orders and services and are willing to work with us as the nature of library service evolves. In my experience, this ability stems from the work they put in to build foundational relationships and understanding the services that are important to libraries.
Mackin is consistent in upholding their standards of fulfillment. Their fill rate is an amazing ninety-nine percent of the orders we submit to them, and their customer service representatives engage with us proactively when items are not available. Their processing is high quality, both their services, such as MackinBound binding, and their adherence to our guidelines for customized processing for our institution. Their delivery time for shipping is consistent from the point of invoicing, and that assists our staff with internal planning for the incoming material.
I highly recommend Mackin Educational Resources as a vendor and a partner in providing high-quality material to our library patrons.”

Acquisitions Supervisor, King County Library System

“Thank you all so much – everything is looking awesome! It’s like Christmas in July, I’m so excited. I’ve been using the system the last two weeks as I work in the library, and I couldn’t be happier with the product!! Genrefication has been a breeze.”

“The large collection of Maker products, kits and books from Mackin has afforded students in Milwaukee Public Schools the opportunity to learn and engage in creative thinking within content areas. The maker movement inspired us to pursue implementing MackinMaker in our school libraries to reinforce concepts such as force and motion and solve complex problems. During our MackinMaker selection process, the Mackin representatives were instrumental in working with us to curate maker kits and maker books to fit our student interests, curriculum, and grade levels. Furthermore, they worked closely with us to recommend products that align with our space requirements, technology infrastructure, and circulation needs. Mackin representatives are very responsive with the continued follow up support we receive in terms of phone/email support and on-site support. The personalized professional development sessions are well received by our library staff. We are extremely pleased with the product selections, customer service, and professional development opportunities.”
“Your customer service was the best!”
“Your packers are simply superior to all other book vendor packers … Amazon could learn a thing or two!”
“It has been my pleasure to work with you; after 10 years with another vendor, I can tell you that based on this experience, I am a Mackin customer from here forward. Thank you so much for making something I enjoy (ordering materials) more enjoyable.”

“This was by far the best PD I’ve received in my 11 years here. Exciting and overwhelming at the same time but definitely reinforces a lot of the ideas we have been trying to promote at our school for the last couple years. Jen, you are amazing! Thanks!”
“So grateful for an excellent knowledgeable trainer and to see my team embrace the change!”
