Wikipedia:External links
For a proposed change to the external links policy, see Wikipedia:External links/temp
In general, external links should be accessible by the widest audience possible. That is, try to avoid sites requiring payment, registration, or extra applications (Flash, Java, etc.) to see the relevant content, at least if there is a simpler site available. If the best/only site does have such requirements, it is best to include a note to that effect. For people with a slow connection, also mention the size if that is large. Examples: "(requires Java)", "(1 MB PDF file)", "(requires registration)". The same applies to any sites with ads that spawn new windows.
