This volume of the BMS is number 150. When we took over as editors of the journal, over three years ago now, we had considered preparing an anniversary issue for this occasion. The editorial board discussed several projects before eventually deciding not to have too many commemorations. When the BMS’s founding team had passed on the baton, we had already published two prefaces – one by Karl van Meter and the other by Marie-Ange Schiltz – discussing the journal’s history. They can be found in issue number 137–138.

这不是周年纪念日！

BMS的本册数量为150。三年前，当我们接任该期刊的编辑时，我们曾考虑过为此准备周年纪念刊。在最终决定不进行过多纪念之前，编辑委员会讨论了几个项目。当BMS的创始团队通过接力棒时，我们已经发表了两篇序言，其中一篇由Karl van Meter撰写，另一篇由Marie-Ange Schiltz撰写，讨论了该期刊的历史。可以在第137-138期找到它们。
