Thanks for reporting this issue! You're right that the app wasn't recognizing several NBG51 abbreviations like "1 Kor." - we've now fixed this for the next app update.
What's changing
You can see the current Dutch book patterns here:

And the updated version (coming in the next release):
https://gitlab.com/remem-me/app/-/blob/develop/assets/l10n/nl_books.json
NBG51 abbreviations now supported
The following abbreviations will be recognized in the next update:
| Abbreviation | Book |
| 1 Kor. / 2 Kor. | Korinthiërs |
| Recht. | Richteren (Judges) |
| Marc. | Markus |
| Luc. | Lukas |
| Ezech. | Ezechiël |
| Klaagl. | Klaagliederen |
| Hebr. | Hebreeën |
| 1 Tes. / 2 Tes. | Thessalonicenzen |
| Filip. | Filippenzen |
| Filem. | Filemon |
| Hoogl. | Hooglied |
| 1 Petr. / 2 Petr. | Petrus |
We've also added support for:
- Period format for numbered books: "1. Kor" or "1. Sam"
- Short forms: Gn, Mk, Lk, etc.
For your CSV import
Option 1: Wait for the update
The next app release will include these fixes. After updating, your NBG51 abbreviations should work correctly.
Option 2: Adjust your CSV now
If you want to import before the update, you can use abbreviations that the current version already recognizes:
| Instead of | Use |
| 1 Kor. | 1 Ko |
| Recht. | Ri |
| Marc. | Mk |
| Luc. | Luk |
| Ezech. | Ez |
| Klaagl. | Kl |
| Hebr. | Heb |
| 1 Tes. | 1 Th |
| Filip. | Fil |
Or use the full Dutch book names (Genesis, Exodus, etc.) which are always recognized.
