Carlinville has long been a site of Illinois history, and has played host to many presidential hopefuls via campaign stops at a time in American history when railway routes produced many visits by politicians. Perhaps the largest and most important hallmark of Carlinville's history is its courthouse, the largest built outside of New York City at the time of its erection. Built in 1870 and designed by famous state capitol building architect Elijah E. Myers, the construction of Carlinville's courthouse produced its candidacy for the location of the State Capitol. Locally, it is known as "The Million Dollar Courthouse" due to its cost overruns at the time it was built.
In the early 1900s Carlinville became the site of a great many Sears Catalog Homes. An entire neighborhood was constructed of the homes and was funded, in 1918, by Standard Oil of Indiana for its mineworkers in Carlinville, at a cost of approximately 1 million dollars. In gratitude, Sears, Roebuck named one of its house models the "Carlin." Today 150 of the original 156 homes still exist, the largest single repository of Sears Catalog Homes in the United States.
One notable resident of Carlinville was American entomologist Charles Robertson, who carried out what is still the single most intensive study of flower-visiting insects of a single locality (Carlinville), culminating in a 221-page book published in 1928 under the title Flowers and Insects. From among the specimens he collected in the process of doing this study, he named over 100 new species of bees and wasps. Scientists in 1970–1972 did a similar survey, and found that most of the bees noted by Robertson were still present. This is presumably due to the existence of bee habitat in hedgerows, on slopes, and in other non-agricultural land in the survey area.
Other notable Carlinvillians include nature writer and novelist Mary Hunter Austin, once called "the most intelligent woman in America" by H.G. Wells, and current resident and scholar Andy Freehill (author of The Ontology of the Living Deity).

Illinois Route 4 directly passes through Carlinville. Interstate 55 is also within 12 miles (19 km) of the city. Illinois Route 108 Passes through Carlinville from Interstate 55 to the East, to Kampsville, Illinois, where it crosses the Illinois River on a free, state-operated ferry. Alongside a developed road network, the Carlinville Amtrak station is also served directly by five daily trains, offering easy access south to St. Louis and north to Springfield and Chicago.
Freight rail service is provided by the Union Pacific Railroad, formerly the Gulf, Mobile and Ohio, the Illinois Central Gulf, the Chicago, Missouri and Western, and the Southern Pacific Chicago - St. Louis Railways. The main line of the GM&O passed through Carlinville.
The Illinois Terminal Railroad, an electric interurban to St. Louis from Springfied that once provided both freight and passenger service, passed down the middle of Carlinville's West Street. It was still operating freight trains on West Street to a nearby grain elevator into the 1970s. Its trestle crossing Goat Hollow south of Carlinville burned severing the line, which was then abandoned. A small portion of the line is used by Monterey Coal Co. mine to connect with the former Chicago and North Western Transportation Company L & M District], serving coal-fired power plants.
