My first bit of advice is to get signed up to Museum 2.0. When this excellent blog appears into my email it's always worth a read. It sometimes challenges my preconceptions, often asks questions which I can apply to myself, my work or venue, and is a very engaging site, taking the discussion to twitter, and bringing in quotes from folks chatting on there.
My second blog suggestion for extra ideas in 2020 - ExhibiTricks!
I can't do better than the description Paul uses himself: "Tricks of the Trade" about Exhibits (and Museums.) Useful information and resources for museum exhibition design and exhibit development."
Sign up, and enjoy everything from advice on label writing and graphics, to musings on real life experiences of best and bad practices.
That may sound dry, but oh boy, it's often eye opening and always accessibly presented - well worth signing up!
