I copied the relevant parts of the wiki pages for both Marshall and Barnett. This may be repetition, but at least they do have references to check.
http://indianajones.wikia.com/wiki/Marshall_College
Marshall College is a college in Bedford, Connecticut. It was one of the schools where Indiana Jones taught as a professor of archaeology. Marcus Brody served as Dean of Students and was later succeeded by Charles Stanforth. Brody also curator of the museum here and paid for many of the minor artifacts that Jones retrieved on his expeditions. The college was governed by a Board of Regents.
Indiana Jones was teaching at Marshall College as early as 1925[3]. Just as the spring term in 1931 ended, he and Marcus Brody became involved in the quest to recover the stolen Wohat Statues, which led to Jones finding the Invincible Ruby of Ali Bey. Helen and Helen's friend were two of Jones' students that semester.[4] By 1933, he had switched to Princeton University[3]. By 1935, he had returned to Marshall College. In 1936, his performance as a professor for archaeology was evaluated by Charles Kennedy.
In 1936, Jones was teaching Archaeology 101, when the college received some US government visitors: Eaton and Musgrove. Meeting in a large classroom, they enlisted Jones' help in tracking down the whereabouts of Abner Ravenwood, in a search to prevent the Nazis from finding the Ark of the Covenant.
By 1938, Jones had left Marshall College for Barnett College, but by the 1950s, had returned to the Archaeology Department at Marshall.
Behind the scenes
The college is named in honor of Frank Marshall, a regular collaborator with Spielberg and a producer on all four films. When the college scenes were originally shot for Raiders of the Lost Ark, there was no perceived need to name the college, but when the novelization was being written, the author, Campbell Black, needed to call the college something, so the name Marshall College was conceived. Marshall himself forgot this until, when the film crew returned to shoot the college scenes for Indiana Jones and the Kingdom of the Crystal Skull, he began seeing his name everywhere.
External shots of the Marshall College campus were filmed at Yale University in New Haven, Connecticut, during July, 2007 for the film Indiana Jones and the Kingdom of the Crystal Skull. The Yale Commons was turned into the Marshall College library interior setting, while the entrance to the Sterling Memorial Library served as the Marshall College library entrance. William L. Harkness Hall was used for the archaeology lecture hall and corridor. The Old Campus quad was used for the protest and car crash scene, and Branford College was also used for some of the campus shots.

Established in 1823[1],
Barnett College was a college in Fairfield, New York. Indiana Jones was a professor of archaeology there for several years, starting in 1937[2]. Jones' office was located in Hamilton Hall. Marcus Brody also worked at the college, in conjunction with his duties at the National Museum.
Barnett College housed the Dunlop Collection, a set of important historical documents, including one of two known copies of Hermocrates.
Adventures at Barnett College
In the fall of 1937, Snedly assigned Professor Jones three freshman "Archaeology 101" sections, and transfered his seminar "Origins of the Incas 201" to visiting professor Francisca Uribe Del Arco. Despite starting off on the wrong foot with Uribe, Jones and Uribe teamed up after attackers tried to steal a package from Uribe's brother. As the semester was starting, the pair were given a sabbatical to journey to South America to track down the Chimu Taya Arms.
After successfully retrieving the Cross of Coronado off of the coast of Portugal in 1938, Jones met with Marcus Brody at the college to discuss the National Museum's acquisition of the artifact. Jones then met with his secretary Irene and pushed his way through a room of eager students to seek sanctuary in his office. Climbing out the window to avoid the students, he was found by men who took him to New York City to meet Walter Donovan.
In 1939, Jones was at the college when he was approached by a gentleman who needed help with a mysterious artifact. After Jones had realized that it was an Horned Statue from Atlantis and opened it to reveal a bead of orichalcum, the stranger robbed Jones of the statue and escaped. Jones found a clue leading to Sophia Hapgood, and headed off to New York City to find her before the Nazis could. Jones and Hapgood later returned to the college to view a copy of Hermocrates to help them find their way to Atlantis via Monte Carlo and Algeria. After the discovery and destruction of Atlantis, Jones and Hapgood returned to Barnett College and watched a football game, where the winning interception made by Jerry Travis, had been predicted by Hapgood.
Address
When Henry Jones mailed the Grail diary to Indiana, he sent the package to the following address:
Prof. Indiana Jones
Barnett College
Hamilton Hall
Grove Avenue
Fairfield, New York
Behind the scenes
Barnett College is introduced in Indiana Jones and the Last Crusade, and also appears in the video game Indiana Jones and the Fate of Atlantis (the events of which take place in 1939, one year after Last Crusade). It is unclear why Dr. Jones began teaching at Barnett or why he moved back to Marshall, which he returns to sometime prior to the events of Indiana Jones and the Kingdom of the Crystal Skull.
In LEGO Indiana Jones: The Original Adventures, Barnett College serves as a central hub.
While the College's location in Fairfield is first seen on the package containing the Grail diary, which is then shown to be in central New York on a map in Indiana Jones and the Fate of Atlantis, Indiana Jones: The Ultimate Guide places the college as much closer to New York City.
