TDC, or Thai Digital Collection, is a project under ThaiLIS aimed at providing access to a full-text document database. This database includes theses and research reports by professors, collected from universities nationwide. Students, faculty members, and staff can access the service from computers located within member libraries. Details about member libraries can be found by selecting the university/institution option.

Currently, the data migration from the old system to the new system has been completed. Additionally, training sessions on system usage and data entry have been conducted for new members, such as private universities and other organizations. The objective is to share knowledge and disseminate various works to society, allowing this knowledge to be utilized for further development and to contribute to the advancement of the country.
