Cook Memorial Library
Also known as: Ansel B. Cook Home; Victorian Museum

Why it's listed
Built in 1878 at 413 North Milwaukee Avenue in Libertyville, this house began as the country residence of Ansel B. Cook, a Connecticut-born stonemason who became a contractor, state legislator and Chicago alderman. Chicago architect William W. Boyington is thought to have designed it. Original features include a limestone basement, seven marble fireplaces, octagonal bays with angled windows, a Stick Style front stairway and Queen Anne entry doors. Cook's will directed that his home become a library and memorial hall. After his widow's death, the village opened it as the Cook Memorial Library in 1921, when the wood siding was covered with stucco and a four-column Classical Revival portico replaced the original porch. Plans in 1939 and 1963 that would have altered or overshadowed the house were not carried out. A 1968 addition stands to the west, set back and joined by a link. Today the building serves as a museum, and the chimneys, roof and siding were restored in 1998.
Significance in brief: The house was built for Ansel B. Cook, a stonemason, contractor and Chicago alderman, and is thought to have been designed by architect William W. Boyington. Cook willed it to the village as a library and memorial hall, and it opened as the Cook Memorial Library in 1921. The 1921 stucco and Classical Revival portico, together with original details such as fireplaces, stairway and trim, are described as retaining its integrity despite the non-contributing 1968 addition.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
