Missing Op.30 No.1 (BI105-1op30-1)

[MarkGotham]

Hi all,

Thanks for the repo!

I'm trying to triangulate yours with existing ones and mostly yours is larger (includes more works), but apparently missing the Op.30 No.1. That's noticeable partly because you include the Op.30 No.2–4.

Hope that helps! I'll let you know if I come across any more.
