This is a very cool and pretty notebook! I think the mix of grid and lined paper is a little odd, but also very useful! I didn't get a confirmation that it was being shipped (just got a message immediately after ordering it) but it arrived within about ten days. Personally i plan on just using this notebook for general school use, but i think it would also be well suited for any kind of linguistics related notes; the grid pages could be used for phonological or grammatical tables while the lined pages are suited for glosses or just general notes.
