In Word 2010, my reference list includes the Ref Type field whenever I use a type other than Journal. For example:
(1) US Congress. 100th Congress Orphan Drug Act Amendment. 1988.
Ref Type: Bill/Resolution
(2) Morel PCH, Schollum LM, Buwalda TT, Pearson G. Digestibility of bovine immunoglobulin in the piglet. In: Hennesey DP, Cranwell PD, eds. Manipulating pig production V . Werribee, Australia: Australasian Pig Science Association; 1995;181.
(3) Perez-Bosque A, Pelegri C, Vicario M et al. Dietary plasma protein affects the immune response of weaned rats challenged with S. aureus Superantigen B. J Nutr 2004;134:2667-2672.
(4) US Food and Drug Administration. Agency Response Letter GRAS Notice No. GRN 000255. 2008. 10-29-2012.
Ref Type: Online Source
I tried removing it using Tools-> Field and Type Edit, but the Ref Type field is shaded and listed as mandatory. Can someone please let me know how to lose that field?
