A deposit can be shared by several users (by co-authors for instance).

A shared deposit is available in each user’s individual space, thus allowing them to view statistics, among other things. Ownership sharing is useful to avoid duplicate entries.

You can claim the property rights of a deposit directly in the deposit’s page.

Yes, you can select the classification pertaining to the discipline.
A JEL classification entry field is displayed if the field “”Humanities and Social Sciences/Economies and finances” or “Quantitative Finance” have been selected

An ACM classification entry field is displayed if the field “Computer Science” has been selected.

One document may contain several identifiers.

Type in the identifier, select the identifier type, click on the plus button.

By filling the Identifier field, you enable the automatic capture of the metadata associated to this identifier. The form will be filled by  the metadata.

The system retrieves the metadatas which are associated with the DOI in the CrossRef database.

It may be possible that this database supplied no metadata: either the identifier is erroneous, or the publisher does not have or not still informed metadatas.

The title on the HAL cover page is based on the chosen language (metadata : fulltext language). If you have described your title in multiple languages, the title will be the one corresponding to this metadata. You can modify this field in your deposit.

These metadata are related to a reference material :

  • green : valid. Please select a valid item : for an affiliation or a journal the item has been verified. For an author : the IdHAL has been created and the item is the one chosen by the author.
  • yellow : closed, no more available. You can select the item if it matches the metadata. The item has been verified and updated in the reference material. For an author the yellow item matches an author with IdHAL but is is not the item by default.
  • red : to be validated.

To be entitled to the arXiv transfer feature, you must fulfil the following conditions with your deposit : a file is mandatory, English abstract, specific domains, no arXiv identifier.

All LaTeX source files are to be deposited (do not forget the image files). It is recommended to use the LaTeX compilation button to check that HAL and arXiv have the necessary files. The maximum size per file is 3MB each and 10 MB total.

Please make sure that the .bbl file is included in your deposit. ArXiv does not accept .bib files, only .bbl.

The transfer feature appears at the last step of the deposit process. After the transfer, the deposit is then moderated by the arXiv teams.

This may be for several reasons why your cited references do not appear : your file may have been digitized thus it can not be used.

Your paper does not meet the criteria of the archive.

You must have received an email from the verification team with more details.

We do not accept : University Post-Viva dissertations, resumes, table of contents, biographies, list of references, newsletters.

In order to submit a simple bibliographic reference (without full-text) you only need to click on one of the following step while you make a new submission.

The first stage will be automatically validated and you just have to complete the metadata and the author(s) data.

Please make sure that your submission is complete and then click on “Upload”

Your bibliographic reference will be automatically online.

As explained in the HAL homepage any deposit is definitive, no withdrawals will be made after the on-line posting of the publication because of the sustainability of our links.

HAL offers the sustainability of the submissions’ links by ensuring that URLs like : hal.archives-ouvertes.fr/ or hal.archives-ouvertes.fr//file_name will always redirect to the document, regardless of the developments of HAL.
Nevertheless, the sustainability of the links which contain a file name hal.archives-ouvertes.fr//file_name relies on the condition that the file will not be deleted.

However, if your article is due to be published later, we could apply an embargo on your file. This way the paper itself is not accessible but the bibliographic record remains on our website.

If your submission requires a correction you can ‘Modify the metadata’ or ‘Deposit a new version’ from the My space/My deposits menu.

Each deposit with a file is manually checked before to be posted online. Usually the process to moderate a paper lasts around a week. This period could be subjected to variation when we receive a large amount of submissions.

The maximum size of a file is 200MB. Note that this size may vary slightly depending on the traffic on the servers. A message will be displayed if there is a size problem when uploading your file.

The size of the file is not blocking: you can use the ftp storage to temporarily store your files. They will be automatically displayed when you make a deposit (tab: Select the files from the ftp area).

Your article has been retracted but you had submitted the full text to HAL. To warn the readers, you can add a version to this deposit: the file can contain either the notice of retraction (example), or the full text of the article with the mention Retracted/Retracted (example).

To complete the information, we suggest you add the mention “Retracted” in the title field of the deposit.

To report an erratum, you can add the file containing the erratum as an annex to the deposit describing the original document that is being corrected.

To provide more complete information to readers, you can also add the publication references of the erratum in the metadata (e.g. Comment field, or See also field for an url).

Another solution is to take advantage of the benefits of an open archive by uploading a file containing the full text of the document with embedded corrections (use Add a new version).

See Managing one’s deposit

To submit a blog post or article, the type of document to choose is “Scientific blog post”. The name of the blog and the publication date are mandatory.
The content of the article must be a written article. For example, congress announcements and seminar programs are not accepted.
It cannot be a publication on a website (choose “Other publication”)

The document type Book review is a subtype of “Journal article”. Move the mouse over the arrow next to this document type to unfold the subtypes: you can select “Book review”.
The publication date and the title of the journal are mandatory.

IdHAL and CV

Creating an IdHAL is not mandatory to submit your paper on HAL.

In order to create your IdHAL you need to have at least one paper available on HAL. This procedure will create your author form. Then you can associate it to your IdHAL.

The IdHAL creation must remain unique, since it is associated to your account and it is used to create the CV’s URL .

You can not change it.

In order to remove a deposit from your CV, go to My Space / My IdHAL and then in ‘Author forms associated with your IdHAL’ click on the list icon ‘consult the documents associated with this author form’. The list of the publications from an author form will be shown. It is now possible to check your publications and uncheck those of similar names. Save your modifications.

Your CV will be updated on the next day.

The HAL CV automatically refers to the list of your publications. You can edit it from My Space / My CV add a title and a brief presentation.

Please make sure :

  • that your text does not exceed the limit of 65 000 characters.
  • that you did not copy/paste from Word. Use preferably a text editor to copy your presentation and then select the page layout style.

Select your language and click on ‘+’. You can choose which publications you want to appear as well as the widgets.

Don’t forget to save it.

The list of your publications will be automatically updated if you make a new deposit.

The author form in some deposits may not be associated to your IdHAL.

You need to associate it. Go to My Space / My Profile / Configure my IdHAL and in ‘Author forms associated with your IdHAL’ click on ‘search author forms’, check the publications by using the list icon ‘consult the documents associated with this author form’ and then click on the ‘+’ button. Then Save.


Refuser un dépôt est à utiliser si le dépôt ne correspond pas aux critères de HAL (mémoire par ex). Le dépôt est conservé dans la base de données.

Supprimer un dépôt efface le dépôt de la base de données : il est utiliser comme alternative à la fonctionnalité Transformer en notice lorsqu’il y a eu ajout de fichier à une notice. Il est en effet impossible de transformer en notice puisque la notice existe déjà. Exemple : ajout d’un fichier contenant le sommaire à une notice décrivant un ouvrage.

Les annotations utilisées pour l’échange entre modérateurs ne sont visibles que d’eux seuls. Elles n’apparaissent pas dans l’historique pour le déposant ou les propriétaires du dépôt.

Dans l’interface de dépôt, vous ne voyez que les dépôts qui correspondent aux critères associés à vos droits de valideur technique, le plus souvent les dépôts effectués dans le portail de votre institution. Si vous avez remis en modération un dépôt qui ne correspond pas à ces critères, il n’apparaîtra pas dans votre interface de modération. Le portail de création du dépôt n’est pas une information affichée, aussi cette fonctionnalité ne doit être utilisée que si vous avez mis en ligne par erreur ou trop vite un dépôt que vous avez traité.

A noter que cette fonctionnalité est à utiliser uniquement si une manipulation doit être faite sur le fichier. Elle ne doit pas être utilisée pour modifier des métadonnées.

Le modérateur doit se poser la question si l’éditeur impose un embargo sur la version postprint d’un article et que la date de publication est au moins inférieure à 6 mois.

Des indices peuvent permettre de distinguer les 2 versions : le nom du fichier (submitted version, preprint/accepted, last version, revised version, postprint) et/ou une mention explicite dans le fichier.

En l’absence d’indices, il n’y a que l’auteur qui peut faire la différence. Le modérateur privilégiera la mise en ligne sans embargo plutôt que demander au déposant.

Le modérateur s’intéresse à la question du financement pour savoir si l’article 30 de la Loi pour une République Numérique peut s’appliquer et ainsi réduire la durée d’embargo imposée par l’éditeur sur la version postprint.

Sont considérés comme fonds publics les dotations de l’État français, des collectivités territoriales ou des établissements publics, des subventions d’agences de financement nationales ou des fonds de l’Union européenne. L’évaluation du financement inclut tous les coûts de la recherche (salaires, hébergement …). Voir aussi Guide d’application de la loi pour une République numérique (art. 30)

L’indice le plus évident est la présence d’un code projet ANR ou d’un projet Européen dans les métadonnées correspondantes.

L’information peut figurer dans le contenu du fichier dans une section intitulée Acknowledgements ou Funding. Le contenu de cette section peut être aussi trouvé sur le site de l’éditeur si l’article est en accès libre ou gratuit.

En l’absence de cette information, la ou les affiliations des co-auteurs peuvent constituer des indices.

En cas de doute, le modérateur applique la durée d’embargo correspondant à celle demandée par l’éditeur, le signale au déposant en lui précisant que l’embargo peut être réduit en fonction du financement de sa recherche (Le déposant devra faire la demande auprès de hal.support@ccsd.cnrs.fr).

Si le fichier déposé contient la version publiée et que le site de l’éditeur indique que le document est en « free access », cela ne signifie pas forcément qu’il est en « open access ». L’accès gratuit n’implique pas forcément que l’on peut diffuser sur HAL la version publiée.

Si aucune licence Creative Commons n’est mentionnée dans le fichier ou sur le site de l’éditeur, il faudra alors chercher l’information sur le site de l’éditeur (authors informations, licencing, etc).

Le répertoire DOAJ (Directory of open access journals) peut être consulté pour vérifier si la revue est en libre accès, ainsi que le DOAB (Directory of open access books) qui indexe les livres en accès libre.

En l’absence d’information, le modérateur demandera au déposant s’il a l’autorisation de l’éditeur.

Tous les articles disponibles gratuitement dans la collection « Open archive » sur Sciencedirect sont sous licence Elsevier. Cette licence ne permet pas la redistribution ou la diffusion dans un entrepôt (voir https://www.elsevier.com/about/policies/open-access-licenses).

Le déposant doit donc obtenir l’autorisation explicite ou bien déposer une version auteur.
