In 1979 the Library was installed in what had been the Gymnasium. The architect Richard Follett, an OG, was in charge of project to turn the old gym into what is now our library. The old gym gallery was extended to form a second floor. This one was walled off and divided into four rooms housing the Administrator and his Staff. The whole of the ground floor was furnished with book-shelves, except for two rooms used by the Librarian as store-rooms, and two others which previously housed gym equipment, which were transformed into Computer Rooms.
Mrs. N. Luaces De Krestchel the former librarian of the Biblioteca Nacional and a graduate from Escuela Nacional de Bibliotecarios, took charge of the library in that same year.
The “new” building was named Jackson Library after the former headmaster of the school R. B. Jackson. However, it had largely been the idea of Mr. M. Garvie, Lockwood Housemaster as well as Head of English, who believed that the College should have a Library which could be an inspiration to the School. An international gathering was organized to raise funds and books that resulted in a total of more than 3,000 volumes which were donated by the OG's worldwide. The most important of the donations was made by the Whitney family. The shelves and files were modeled after the ones in the Mariano Moreno Library, in fact they were made by the same carpenter.
The books were placed in open shelving, which fostered the growth of the collections and helped in their maintenance. The use of the library grew significantly in this new place as it became the favorite room for the pupils to do their homework after school.
That year the use of a new lending system begins. It consisted in each book having an envelope in its back with a data entry card. The Library guardians helped in the production of those cards. The monthly publication of the Library News for teachers and students started at that time too. In 1981, Nora produced an alphabetic catalog of authors for the Spanish books in the “Biblioteca José Hernánez”. The new head of English, Mr. T. D. Baker was put in charge of the activities on Wednesday and of the selection of English books. In 1983 two new changes were made: Claudia De Santis was temporarily employed to start cataloging the collection, and the student had access to a Newspaper Archive that had been collected during the four previous years. By 1984 the school adopted the International Baccalaureate program, and with it a plan of acquisition of library material was developed. In 1985 Nora started to work full-time and Mrs. Mónica Martín, Spanish teacher, was hired as assistant librarian, making the library available for almost eleven hours per day. 
In 1987, while cataloging old books donated by Mr. E. H. Long’s family, a letter hand-written by Charles Darwin to Mr. Long was found inside one of the volumes. The professor Rick Baylis wrote to the Darwinian Society of Cambridge to corroborate the authenticity of the signature. On seeing this, the Society made a tempting offer to buy the letter, but an Old Georgian interested in keeping this valuable material in the school, offered to donate the same amount of money that was divided between the library and the laboratory. That way, the College was able to preserve that “treasure”. The same year, Mr. H. Lorimber donated a computer to help keep up the technical work in the premises.
In 1988 library assistant Mónica Martín resigned and was replaced by Rev. Robert Jordan. 1800 volumes of “José Hernández Library” were reprocessed. Books were catalogued, registered and the proper subject heading added when incorporating the data on the computer. Books started to be placed on shelves following the Dewey Decimal Cataloging System and a topographical record was prepared to illustrate the location of the books on the shelves. Also, some many autographed book were found (like Les souliers de Satin by author Paul Claudel) which were put on exhibition. By 1990, the re-cataloging of the Biblioteca José Hernández was successfully completed and it was decided that when the cataloging of the English collection is completed as well, both collections (English and Spanish) would be together. 
At the end of 1991, Ms. Nora Luaces left the Jackson Library to take over the coordination of the Mariano Moreno Library of Bernal. She was replaced by Ms. Marisa Alonso de Lara, who continued working with Rev. Robert Jordan until 1996, when he left the school.
By 1995 the library started to work as a multimedia center provided with many resources: a very good Reference section, CD-room’s in continual use, and a growing collection of periodicals and magazines. Students used the files of over 90 different topics with newspaper clippings every day. In order to be able to provide a better, faster service to all, the manual filling system was transferred to the MICRO ISIS programme, created for Libraries by UNESCO. In 1996 the installation of a JUKEBOX made it possible to access to several CD-ROM's simultaneously through a network service. Internet began to be used inside the library as well.
