“Thank you again for all your hard work in bringing the facsimile of the Florence Codex of the Cantigas de Santa Maria to Bridwell Library … As you know, I like to show original early books whenever possible, but naturally there is great interest in facsimiles such as this, which allow our students and public to ‘see' and study originals belonging to European libraries from afar. They are perfect for class instruction in the theology school and the departments of history, literature, art history, music, and foreign languages. I believe well-chosen examples will be essential for enhancing the quality of instruction and increasing our students' awareness of their cultural heritage in great books.”
Eric White, Librarian for Rare Books, Perkins School of Theology at Southern Methodist University

“The Special Collections division of Louisiana State University Libraries has been buying books from The Treasured Library and Ernesto Montes since 2000. … Mr. Montes has provided excellent service and the most competitive prices. He has been willing to bring materials to our library so that faculty could see what was being offered and assist me (the curator) in choosing materials best suited to serving faculty and student research needs. On several occasions, because of his contacts in the trade, he has found and offered us copies at very favorable prices.”
Elaine Smith Rare Book Librarian, Louisiana State University
 
“It is a privilege and pleasure to be able to comment on our experience with the Treasured Library. I have known their representative, Ernesto Montes, since 2002 when the Latin American Collection at the Yale University Library purchased a facsimile of an important work entitled ‘Relación de Michoacán.' Our university has highly regarded academic programs in art history, colonial Latin American literature, and history in general, and works such as this one greatly enhance our collections of research materials. Since then, the Yale University Library has purchased several other important works relating to the pre-Hispanic and colonial periods of Latin American history. Mr. Montes' contributions to this entire process are thoughtful and thorough, and they clearly show his devotion and commitment to providing excellent service. His diligent work, sensitivity, and commitment are very appealing to us as librarians as well as our patrons. The Yale scholarly community is very grateful for this great service.”
Cesar Rodriguez, Latin American Collections Librarian, Yale University

“In my role as specialist librarian for the world-renowned Medieval Institute at the University of Notre Dame, I have known Mr. Ernesto Montes -- of the Treasured Library -- professionally approximately seven years. Mr. Montes is very knowledgeable in his chosen field, very good at identifying high-quality worthwhile facsimiles of manuscripts from the Middle Ages (especially, but not exclusively, from Spain), and he is exceptionally good at locating out-of-print facsimiles when our professors make such a special request.”
 Marina Smyth, Librarian of Rare Books, Notre Dame University Medieval Institute

“I gladly write this letter to share with future customers of the Treasured Library. UNC-Chapel Hill has been a customer for the several years that I have been in the position of Latin American and Iberian bibliographer. Through the years our library has purchased many facsimiles from you, and we have been very satisfied with the quality of the products. … and are now in the process of purchasing yet another facsimile from you based on the request of a faculty member who happened to see the facsimile at another university library. I look forward to many more years of continued quality service from you and your company.” 
Teresa Chapa, University of North Carolina at Chapel Hill
