Hi
OberonBard, and welcome.
I'm a Queenslander myself [born in Brisbane] but languishing in New South. Actually, ironically I am within driving distance of the town of Oberon.
Do I take it you are a Shakespeare Buff?
How has the content from the 1930s and onward come to be in the public domain? I thought that US copyright persisted for 95 years? Anyway, it's great to have access to a wonderful curated resource like this.
People often ask this question, but often from different directions. I'm not staff, so I'm not an expert
I think it works like this. Someone [or company] has to own the copyright. If the company didn't protect the copyright in the first place or just went out of business without renewing copyright or selling it to another company, then it becomes
PD. [In the public domain] If you own copyright and you have good lawyers you can renew it indefinitely. So anything that was published before about 1963 in English speaking countries, that you don't see on CB+,either hasn't been found to upload to the site or is not PD. Clear as mud.
Enjoy the site - and if you have any rare Australian comics that are PD - they could find a home here.
Welcome, enjoy and please join in.
Cheers!
