I really have tried for a long time to understand how this could work, as it seems like it should be relatively simple, but I can't figure it out, and would really appreciate some guidance.
We would like people to be able to download digital formats (.pdf & .epub & .mobi) directly from the site, but would like the paperback format TO HAVE A TAB at top of the catalog entry (like 'synopsis' and 'download') and also in the dropdown side menus, yet we do not have proofs or files on that tab for download, instead we'd like to have a little bit of text about our print co-publisher, and then a link to their 'createspace' page so that people can leave our site to go there and purchase. Not sure why this is so difficult, but it really is.
Any help would be MOST appreciated. Our site is at http://press.radicalcriminology.org
