Students up to 1912
Students up to 1912 can be found in the register of GCI's 100th anniversary book. The list is divided into male and female students. The male list, in turn, is divided into two parts: before 1864, which is not complete, and 1864–1912. Women were admitted to GCI in 1864. The list includes name, year of birth, year of graduation.
Students between the years 1904–1992 can be found in annual class lists. These can be found in the library's book stacks. The lists contain name, address and possibly telephone number.
Female students who are members of the GCI/GIH Association can be found in the GCI Association's yearbook, which contains registers.
In 2016, there is also a list sorted by year of departure from GCI/GIH. This list includes female students who are members of the association.
