Great word! Thank you. Here's an interesting example I found online and translated it into English. (I hope it's correct!)
Читала словари, справочники, энциклопедии и стала по мере течения Волги настоящим кладезем знаний.
I read dictionaries, reference books, and encyclopedias and became a regular treasure trove of knowledge in all things related to the flow of the Volga.

Thanks Улий! I would say "a real treasure trove of knowledge" - what do you think?

You’re welcome!

REGULAR means REAL in comparisons, especially with famous people: “You look like a regular Beyoncé in that dress.” -or- “My son’s a science whiz – a regular Einstein.” -or- “ I can’t wait till you shave that beard off. You’re creeping me out. You look like a regular Rasputin!”

Good to know!
