We have been discussing ways to stop this happening again but it does not matter what we do to protect these patterns, people will find a way around it.  Adding something to the scan will only help prove that it was originally scanned for the library but will not stop people trying in the first place.

However, if everybody was to advertise the APL as much as possible, these copies would not sell as most people would know that they could get them for free.  If every body could add a link to their site, blog or even your siggy, then the word would get around.

You can either copy and paste the following html into your web page -

It will look like this ~ 

Or you can save the logo and use it to link to -   http://www.antiquepatternlibrary.org

Or just insert a text link

Thanks for your help!
