Since its creation at the end of the 1990’s, the EELS database has gathered more than 200 spectra covering 35 elements of the periodic table, becoming the largest open-access electronic repository of spectra from Electron Energy-Loss Spectroscopy and X-ray Absorption Spectroscopy experiments.1 The EELS database is now a common tool used by spectroscopists, theoreticians, students and private firms as a reference catalog for fine structures and data-treatment analyzes2-4 and has been referenced by more than 30 papers.

Much of this success is due to the open-access nature of the database. The database depends on voluntary user contributions; to encourage these contributions, we have performed a major update of the website which is now accessible at http://eelsdb.eu/. The design of the website has been improved (Figure 1) and several new functions have been implemented, including a plotting function (Figure 2) which allows the online comparison of spectra before downloading. The new design gives greater emphasis on the original work of the contributors by strongly highlighting their papers. In addition of the database itself, users can post and manage job adverts and read the latest news and events regarding the EELS community. All these improvements will be discussed further in the poster details.

The authors would like to thank the IMN and CEMES laboratories, the European microscopy network ESTEEM 2, the French microscopy network METSA and the French microscopy society Sfµ, for the funding. The authors warmly acknowledge everyone who has contributed to the database.
