Zentralblatt going open access: https://euro-math-soc.eu/news/19/12/17/zbmath-become-open-access
I mostly use a mix of Google Scholar (for searching), MathSciNet (for more targeted searches, reviews, and high-quality bibtex), and DBLP (for bibtex of CS papers not in MathSciNet) but maybe this will convince me to add ZB into the mix.
@11011110 Awesome! I refused to review for zbMATH about a month ago because they were closed access. This is great news!
