Fundamental changes in the functioning of the library were brought about by computerization initiated in 1990, when library employees Wojciech Charkin and Lech Zięborak developed the "Concept of computerization of library and information processes in the Main Library". The software was selected, IBM PC computers were configured and installed, and a computer network diagram in the library was developed.
Since 1991, the Main Library has been implementing and developing its own integrated computer system, APIS, which enables the creation of databases regarding compact and serial publications. The system guaranteed full access to information about the library's resources, as well as their sharing. In 1997, a network system for sharing databases on CD-ROMs called Infoware CD/HD from Info Technology Supply was installed and launched. The system enabled access to CD-ROM databases located in the Library via the University of Technology's computer network and the Tricity Academic Computer Network (TASK).
Originally, CD collections were cheaper than the Internet because it was based on telephony, which changed over time, which is why journals, standards and patents appeared on CDs first, but they still took up a lot of space. Later, some of the collections (journals, books and patents) were made available online, separately or, more and more often, in the form of scientific databases - bibliographic, abstract and full-text (with the possibility of downloading or printing individual texts, articles or book chapters).
In the following years, computer systems, catalogues and digital collection resources were developed. Social media played an increasingly important role, and trainings were organized from the basic ones - for students starting their studies - to highly specialized for PhD students and employees of the University of Technology. The library organized exhibitions, meetings and scientific conferences. At the same time, traditional collections were developed, new rooms for the Library's branches were created and the reading rooms in the Main Library were transformed, adapting them to the changing needs.
