Essentially, nothing can stop an end user doing that. Yes, there are scripts that might slow them down, but nothing will stop them. Especially if you still want them indexed by search engines.
This has been coded several times in javascript and a quick search will yield plenty of returns. Do not forget, there are legitimate reasons for someone to try to "copy and paste" material from your website. Making it harder just adds to the annoyance level of sites and some of those "real" visitors may not return. The people you should worry about are not the copy and paste crowd. Unfortunately, the only way to defeat them is to never publish on the web. On one of my sites, I allow visitors to see portions of articles and I let subscribers see the full content of articles. You may also want to consider this as an opportunity. What if you allowed people to use material from your website as long as they included a link back as part of the credit. Your focus changes from stopping any use of material to only stopping those ignorant people who refuse to provide the required link back in exchange for using your material. This could result in lots of high quality back links, which helps elevate your ranking in search engines, and gets links to your website in front of other people with similar interests. This type of guerilla marketing is a sophisticated form of contextual advertising where you barter content for high visibility ad space that users want to view instead of wanting to block.
maybe what you could do is write it out reversed... (which would only deter a few people, or slow them down in reality). I have done this technique for hiding Email addresses. have the server-side script write out the email addresses backwords, then javascript, write them out reversed. This way your written HTML is reversed but the content cant be view-source, copy/pasteable directly. Their are also some JS scripts to disable KeyStrokes or disable the right-click context menu.
Thx, good point. This means I have to look for copys of my site frequently and then write them threatening them if they dont make a backlink . But this is actually a good thought.
Maybe try out http://www.copyscape.com/ . I don't know how good it is, but even if it isn't, I'm sure there are other companies out there that do this kind of thing...
