I know that according to halacha, any notebook (etc.) which has the name of G-d written in it needs to be buried in geniza.
Does the same apply to abbreviations of G-d's name? For example, writing "Gd" B"H (for Baruch Hashem) and BS"D (for B'siyata dishmaya).
Are there sources which discuss whether these abbreviations also need to be buried?
