I've gotten a large collection of post cards from the 1900s-1950s what would be best way to track which ones I have

A few more sub questions

Any good resources about collecting and preserving these?

If I find a number of obscure ones what’s the best way to scan them in bulk to preserve them

Are there any good tools to convert cursive to print text (I can read cursive but not as well as I’d like, and some of these are very fine cursive writings)

Any other tips I should know?

Thanks!
