Disclaimer
This site is a directory: the great majority of each page is another site's name, what it is for, and where to find it. Here is what that shape of site cannot promise.
What we provide
We provide link entries, their names and a one-line description, plus notes on how each section is best used. We do not host, republish or cache any third party's content and do not act as an agent for their services.
Every description is our own editorial summary of what the entry is normally for. It is not the operator's official wording and is not an assessment of their quality.
No guarantee of accuracy or currency
Sites rename themselves, move domains, redesign, start charging, restrict access or shut down entirely — all of it routine. This is a hand-maintained personal project, so no entry can be guaranteed accurate, complete or working at any given moment.
We make no express or implied warranty about the availability of outbound links, the correctness of third-party content, or the security of third-party services. If you find a dead link or a wrong description, write to us and we will check and fix or remove it.
Not a recommendation or professional advice
Being listed here is not a recommendation, endorsement or approval of any third-party site, product, service or organisation — and neither is the appearance of an advertisement.
The content is intended for general study and research. It is not legal, medical, financial or any other kind of professional advice. For decisions that matter, consult a qualified professional and rely on authoritative sources.
Third-party content and intellectual property
Names, trademarks, logos and assets of listed sites belong to their respective owners; we use them only to identify and link to those sites, and claim no rights over them.
We do not list or provide resources that require cracking or licence circumvention or that distribute unauthorised copies; sites openly offering pirated film, pirated ebooks or cracked software are outside our listing scope. If you believe an entry or a passage here infringes your rights, write to jiangnan.chemistry@gmail.com with the exact URL and we will deal with it promptly after checking — usually by correcting the wording or removing the entry outright.
Risks of visiting third-party sites
Once you follow an outbound link, your visit, your cookies and the handling of your data fall under that site's policies and terms. We cannot see, influence or answer for any of it. Judge the risk yourself on those sites, especially before downloading files, submitting personal information or making a payment.
We do not warrant the safety of files downloaded through outbound links; scan them and keep backups as you normally would.
If something is wrong
Dead links, outdated descriptions, listing suggestions, removal and infringement requests all go to jiangnan.chemistry@gmail.com; naming the exact URL makes it much faster to act on.
