A locked door and myriad treasures beyond, in vast rooms deemed unusable at Boston Public Library

The Boston Public Library is initiating a major renovation of its McKim Building, which has suffered extensive deterioration, leaving nearly 40% of the third floor unusable. President David Leonard stated that the project must not only protect the library's collections but also enhance public accessibility. Recently, the library received a $5. 5 million donation to study the building's systems and develop a renovation plan. The McKim Building, designed by architect Charles Follen McKim, is nearly 130 years old and is considered an architectural gem.

Beth Prindle, the library's director of research and special collections, called the renovation a "once in a multiple-generation opportunity" for future stewardship of the collection. The library has previously invested in major capital projects, including a $78 million renovation of its lending library in 2016. The current efforts aim to modernize the space while respecting its historical significance. Library officials hope to complete the five-year planning phase before moving into the design phase of the renovation.
