To allow you to make optimal use of the Noldus bibliography database, we are constantly looking for publications that are not yet included. If you have published any papers about research in which any of the Noldus products were used, please be so kind as to send us a copy. If reprints are not available, you can also send an e-mail with the bibliographical reference (and if possible a PDF of the publication). We will then add your publication to the bibliography. Thank you very much for your cooperation!
