Here is the requested EFDSS Declaration for use of it's items. It covers everything, and could not be clearer. This stinks even more now!

I acknowledge that it is my responsibility to obtain any necessary third party consent to reproduce the items supplied by the Library from the owner of any such copyright in the materials, and I enclose a copy of such consent.
I will indemnify the Library against any claim which may be made against it if I fail to obtain an appropriate consent or fail to abide by the terms of consent.
I understand that the EFDSS reserves the right to refuse a licence if use of the material is deemed to infringe on the moral rights of the EFDSS, the creator, or the copyright holder.
I will not use the materials supplied by the Library for any purpose other than that specified in this form.
I will not copy and/or distribute the materials supplied by the Library to a third party.
I undertake to include in the publication an acknowledgement of the Society, naming it as “The English Folk Dance and Song Society”.
I will pay the appropriate fees in respect to licensing as well as any access fees where necessary.
