President Michael D Higgins is to donate an archive of material gathered during his 14 years in office to the University of Galway.
The collection includes personal papers, writings, and correspondence.
It will be catalogued and held by the institution's library and will be made available for public viewing.
Documentation relating to the President’s official function as Head of State is not included as it transfers to the National Archives.
The donation is being formally announced at an event at the University today, during which the Aula Maxima is being renamed in honour of the President.
The hall, which forms part of the original quadrangle there, was built in 1845. It will now be known as the Michael D Higgins Auditorium.
President Higgins said the material in his archive explains his "thinking, motivation, and frustration too".
It is made up of personal data that has helped inform speeches, statements, and other written materials over the past 14 years.
University of Galway is his alma mater and was also the place where he lectured before his entry into politics.
The collection of papers from his first term in office has already been catalogued by archivists.
The donation also includes a selection of books from his personal collection. Some date from the time he was a lecturer in what was then UCG, through to more recent acquisitions.
Others are among those presented to him at events he has attended in an official capacity.
Interim President of the University Peter McHugh said the institute hoped the entire collection would help to "inspire the minds of students and researchers".
It includes edited speech drafts and personal correspondence with a wide and diverse range of individuals.
The collection runs to more than 150 boxes.
President Higgins is not the first Head of State to give their archives to the University.
Former President Mary Robinson donated her papers after her term of office ended while the library also holds a number of collections relating to the first person to hold the role of President - Douglas Hyde.
Both the archive and books will be accessible for research by members of the public in the library’s Special Collections Reading Room.
