Openings database at Chess.com is not user-friendly. For instance, I wanted to read about Sicilian Pelikan variation, and I wasn't able to search for it successfully. Which is a good website to learn chess openings?
Browsing database and reading some articles about the openings are different things. 365.chess.com is good database site, but I assume that, since the OP is paying member, base here should be equally good (if not better). As for a reading, there should be a plenty articles available here, just search the articles. Pelikan is nowadays more known as Sveshikov so you might also try it as a key word in search.
