This is soft question. I decided to ask my question on MathOverflow rather than on academia StackExchange because I believe that the community here is more equipped to answer the question.


The [Graduate Journal of Mathematics](https://gradmath.org/) mentions in its mission-statement that it takes inspiration from a similar journal that was discontinued in 2000: Le Journal des Elèves de l’Ecole Normale Supérieure de Lyon. I have searched about the later journal "Le Journal des Elèves de l’Ecole Normale Supérieure de Lyon" in google but found no active webpage for it.


* Can someone tell me about the journal "Le Journal des Elèves de l’Ecole Normale Supérieure de Lyon" ?
* Why it was discontinued ?


There are there other journals which were also discontinued for publication. For example, [LMS Journal of Computation and Mathematics](https://www.lms.ac.uk/publications/jcm) was discontinued in 2015.

My main motivation for the above questions is the following:

What causes some mathematical journals to discontinue?
At <https://futurelms.wordpress.com/2016/01/14/save-the-lms-journal-of-computation-and-mathematics/> you will find discussion of the decision to close the LMS Journal of Computation and Mathematics. My knowledge is based solely on a brief scan of the documents linked from that page. It seems that some people felt that the papers in the journal were not of high quality and were seldom read. The decision to close was narrowly confirmed by a vote at a special general meeting of the LMS.
