So yes, just the new contributions will be paywalled. And if you if need to access the information: inform your librarian. The rate schedule for universities will be very fair. It's a cheap set-up fee (a single payment). I will even take very fair rates from companies. However, things must change.

So everyone, who now tells me, that he/she leaves: I am fine with your decisions. Without paywalling, there won't be any updates anyway in 2026. And whether I paywall new contributions or just don't publish them, does not make a difference.

TBH there is a reason, why sites like Synarchive or organic-reaction.com are +/- dead. The question is not, whether people leave, the question is, whether I have the opportunity to increase the usefulness of the website or not. And currently (AI, hosting fees etc, share of donations), I must say no.

OK, I now clearly write, that the paywalled DH has aprox. 1/20 of the visitors we have but can finance more than 12 co-workers, while our ad income hardly finances one. Because people don't click or have ads blocked. And companies run ads via google. Do you see the problem or a solution?
