Opinions differ about the origins of the village’s name. Some attribute it to an early resident, Matthew Coe. Others say it is named for the area of Scotland of the same name. It developed in the late 19th century around a railroad stop. Former Chicago mayor Walter S. Gurnee had become president of the line connecting Chicago and Milwaukee, and often bought up and developed land around railroad stops. Thus, one historian believes the name derives from the maiden name of Gurnee’s wife, since Gurnee bought the land in 1867 and began subdivision, although financial problems prevented him from building a home there and he returned to New York for his final years. The village’s first seal was based on the seal of Glencoe, Scotland.

During the late 19th and early 20th centuries, many elegant homes were built in Glencoe. Most notably, the village is home to the world’s third largest collection of Frank Lloyd Wright structures: the Ravine Bluff subdivision contains seven houses, a concrete bridge and three sculptural markers. There are also two larger, individually built homes, located nearby Ravine Bluffs. In addition to Wright, there are houses designed by Howard Van Doren Shaw, David Adler, Robert E. Seyfarth and George Washington Maher, among others.

Glencoe has a Village Manager form of government. It had one of the first public safety departments (combined police/fire/paramedic). In 1921 it adopted the first zoning code in Illinois. Its land-use plan, adopted in 1940, has been adhered to with minor changes since then. Most all nonconforming uses have been eliminated through attrition and it has developed to the allowed uses outlined on the 1940 zoning map. It is predominantly a single-family residential area, with no industrial uses. It has a small cohesive central business district that provides most basic services, including post office, library, Village Hall, performing arts theatre, train station (to Chicago), and other shopping needs.

Since the late 20th century, for 20 years the village has had redevelopment of smaller homes. They have been torn down and replaced by larger homes, spurring debate on historic preservation, the effects of an increasingly wealthy demographic, and rising property taxes.

In addition to such private development, during this time, the village has completed major reconstruction of its street and sidewalk network. The village installed brick sidewalks and period street lights in the business district. Many public buildings have been or are being remodelled or expanded, including the public schools, Village Hall, library, Park District Community Center, and refrigerated outdoor ice rink. The building housing the Glencoe Woman’s Club (formerly Woman’s Library Club) was torn down. It was replaced by a new building, designed by Jeanne Gang, that houses Writers Theatre. The new building opened to the public in 2016. The private golf clubs (Lake Shore Country Club and Skokie Country Club) have also conducted major remodeling, additions, and reconstruction.

The Village of Glencoe is served by the Glencoe Public Library (GPL), located at 320 Park Avenue. Plans for the library’s current location were announced in 1940, with construction costs estimated to be around $90,000. Prior to this new construction, the Glencoe Library operated out of the former Hawthorne School at 654 Greenleaf Avenue; by 1938, library board members felt that the library should have its own dedicated building, and began developing plans for the new structure. The library was designed to “simulate a suburban home,” according to contemporaneous news reports, with meeting rooms, a local history room, and space for 35,000 books built into the original plans for the envisioned Colonial or Georgian style structure. The library opened its Park Avenue location to the public in 1941. In the 1960s, a 20 year plan was launched to enlarge the library facilities in order to double the library’s capacity for materials storage. In recent years, the library has taken on multiple renovation and repair projects, including the enlargement of staff work areas, the replacement of windows, the installation of a new HVAC system, and various other interior projects to improve facilities.

Glencoe Library is a member of the Reaching Across Illinois Library System network as well as the Cooperative Computer Services (CCS) consortium. This allows for reciprocal borrowing for members of other CCS libraries, in addition to the interlibrary loan services Glencoe offers for materials held outside of the consortium. In February 2022, the library reported its own holdings at 73,528 physical items and over 1,323,000 digital items. Glencoe library’s collection is made up of adult, youth, and teen materials including books, DVDs and Blu-Rays, CDs, audiobooks, Roku streaming devices, magazines and newspapers, the Takiff fine arts collection, and a variety of digital resources including e-content and database subscriptions. GPL went fine-free in 2021. As of 2012, 90% of Glencoe residents held library cards, according to census data.

The library offers an events calendar featuring regular story-times and children’s events; book and film discussions; guest lectures by academics and community groups; seasonal reading challenges; Book News (virtual and in-person book reviews by staff); crafting and art classes; and more. In addition, patrons are able to reserve community rooms in the library, get one-on-one technology assistance through the Book-A-Librarian program, and make use of the library’s two 3-D printers.

In response to the Covid-19 pandemic, the library closed briefly in 2020. It reopened with curbside and contactless pickup, as well as virtual programming, in late 2020. Since then, much of the library’s adult programming has moved to virtual events.

The library is supported by the Glencoe Friends of the Library. The Friends host three used book sales each year, sponsor the regular book and film discussions, summer and winter reading challenges, and various other lectures, concerts, fundraisers and events throughout the year.

GPL publishes its own quarterly newsletter, Excerpts, that contains information regarding upcoming programs and events, information about the library, a staff feature, material recommendations and other relevant news.
