This post is an overview of HAL’s activities in 2018. The following statistics show the investment of all in sharing and disseminating publications and scientific data. This reflects the activity of the researchers who upload their files and use the dedicated services. This also reflects the activity of the information managers and librarians who organize activities and training around HAL, as well as those of the local institutional archives which are connected to HAL.

20% growth in the number of deposits with files

The number of  records with supplementary materials (1,647) decreases slightly, while the creation of bibliographic records is still significant with 160,004 new ones in 2018 (16% growth).

10 new institutional portals

In 2018, the network of institutional archives has grown  with 10 new institutions managing a HAL portal : COMUE Paris-Seine, Université de Lille, Université Lyon 1, Université de Lyon 2, Université de Pau et des Pays de l’Adour, Réseau National des Maisons des Sciences de l’Homme, Université Polytechnique Hauts-de-France, EM Lyon, Université de Technologie de Compiègne, CNAM


The collections give a significant visibility while being easier to manage than a portal.  There are currently 6,547 collections built from various criteria: laboratories, ANR or European projects, conferences. In 2018, there was a slight decrease in the number of creations of collections compared to 2017 (-104) but the figure remains high (842 creations), more than 2 new collections per day. This decline does not affect laboratory collections, which continue to grow.
