legal issue about material in groups..

Hi, would it be legal to publish a problem here that you have from a book or magazine, for your students to discuss?

Would it make a difference if you would name the source?

- From Mark Dvoretsky "Book about Harry Potter goes wing gambit" page 86 problem 3 

 

I'm not sure about the rules, but I guess it would not be too wrong, as long you don't publish everything, and you quote the analysis which is not yours. He doesn't own the position

Normally the site where you want to take the content from will have at the bottom of their homepage 'copyright' links and either a Privacy/Legal page or Terms of Service. You need to look there to see what they have said about reposting content from their site elsewhere. Some don't mind as long as you give credit, others do mind. But you do need to check the other site first before reposting anything from their site elsewhere on the net.

Positions aren't copywriteable. However, I'm not so sure how it will be taken if you copy all of the variations.

Analysis is certainly copywriteable, but you'd be fine quoting and citing limited amounts. Certainly not as much as a page, but the odd couple of sentences is fine.

Hi, thanks for your quick answer! I have a closed group for studying endgames based on a book from Mark Dvoretsky. Actually it could be seen as a requirement to have the book. But since all might have different editions it would make life easier for a teacher if one could publish a position without solution for discussion. 

Does this makes a difference?

In any case i will mail  Mark and ask him personally.

No need to ask. Publishing a position is fine, full stop.

This is my way of seeing it as well!
