EATSB Historical Physics Library: Open Access Collection of Physics Texts

This digital library assembles 85 works by 111 authors, all drawn from the long development of physics. Rather than a simple list, the catalogue emphasizes how ideas migrate across specialties: a treatise on mechanics may sit beside an optical study, or an early thermodynamics paper alongside a later field theory. Readers can enter through a single author’s output, follow a thematic thread such as electricity or the atomic hypothesis, or compare works from different centuries that address the same puzzle. The open-access arrangement lets students and researchers trace conceptual shifts without paywalls or institutional logins.
