Since 2019 the ESO Library has a subscription with Overleaf (www.overleaf.com). 

As we only have access to a limited number of accounts, please only request an ESO-provided license if you need the premium features. The main differences between premium and free accounts are 

- option to invite up to 10 collaborators (free accounts: 1 collaborator)

- Dropbox and Github syncing

If you would like to request a license, please contact us at library@eso.org. In case you already have an Overleaf account, make sure your first and family name are registered (go to overleaf.com / Account / Account settings / Update account info) and send us the email you signed up with.

Here is some additional information about the premium account that might be of interest to you:

  • Max. number of collaborator per project: 10
  • Max. number of files per project: 2,000
  • Max. project size: Overleaf states 500MB as a 'fair use' policy. Constantly exceeding this may warrant further scrutiny.
  • Individual file upload max. size: 50MB
  • Max. storage space per account (Collaborator): Overleaf states 10GB for Collaborator accounts as a 'fair use' policy. Constantly exceeding this may warrant further scrutiny.

You can invite collaborators in two ways: either by sending a shareable link or by inviting them by email, i.e. by clicking "Share" and then specify the emails of allowed collaborators. Overleaf suggests this way of sharing. With link-sharing turned off, only users whose emails are listed by the owner can access the project which provides security and privacy, with much greater control.

Overleaf FAQ

What are the differences between a premium and a free account?

See https://www.overleaf.com/user/subscription/plans


I already have an individual subscription (Collaborator or Professional). What do I need to do?

Please cancel you individual plan to avoid it being renewed.


What happens (with my projects) when I leave ESO?

Your account will turn into a free plan account again. In order to make sure that no content is lost, add a second (non-ESO) email to your account before you leave.
