HAL is designed for authors to deposit and thus make publicly available scholarly documents from all academic fields . These documents should be uploaded either by one of the authors with the consent of the others or by an authorized person on their behalf (information specialist or librarian, for example).

HAL is a tool for direct scientific communication between academics . A text posted to HAL should describe completed research work and should meet current scientific requirements in the field concerned, i.e., the content should be comparable to that of a paper that an investigator might submit for publication in a peer-reviewed scientific journal, conference proceedings, etc. A document deposited in HAL will not be subjected to any detailed scientific evaluation - simply a rapid overview, to ensure that it does indeed fall within the category defined above. The CCSD, however, remains free to decide whether to place the document online or not, without necessarily justifying its decision.

An uploaded document does not need to have been published or even to be intended for publication - it may be posted to HAL as long as its scientific content justifies it. But should the article be published, contributors are invited to indicate the relevant bibliographic information and DOI.

HAL will ensure the long term preservation of a deposited document – this latter will be stored there permanently and will receive a stable web address. Thus, like any publication in a traditional scientific journal, it can be cited in other work.

The free online access to these documents provided by HAL is intended to promote the best possible dissemination of research work; the intellectual property remains that of the author(s). Contributors must abide by the rules of good usage prevailing in scientific publications - respect and citation of original work, no intellectual plunder, etc.

Finally, HAL also offers services of a more administrative nature, such as the easy extraction of lists of publications (for an author, laboratory, institution, etc.) in various formats. When a full text file of a published article is not available and in order for these lists to be as complete as possible, a simple "note" that contains merely the bibliographical references may be added to HAL.
