In my experience it is a bit hit or miss, at best. I did note this in the help file:
“Note: When performing the import function, if the are two DOIs found in the first two pages of a PDF document, EndNote will put both DOIs in the DOI field. The PDF is then attached and the file name is put in the Title field.”
I DID NOT get the PDFs downloading from these refs (and noticed that some of the PDFs I had downloaded were NIH Public Access versions and not from the journals website):
Bachmann, M.P., Bartsch, H., Gross, J.K., Maier, S.M., Gross, T.F., Workman, J.L., James, J.A., Farris, A.D., Jung, B., Franke, C., et al. (2006). Autoimmunity as a result of escape from RNA surveillance. J Immunol 177, 1698-1707.
Florens, L., Carozza, M.J., Swanson, S.K., Fournier, M., Coleman, M.K., Workman, J.L., and Washburn, M.P. (2006). Analyzing chromatin remodeling complexes using shotgun proteomics and normalized spectral abundance factors. Methods 40, 303-311.
John, S., Howe, L., Tafrov, S.T., Grant, P.A., Sternglanz, R., and Workman, J.L. (2000). The something about silencing protein, Sas3, is the catalytic subunit of NuA3, a yTAF(II)30-containing HAT complex that interacts with the Spt16 subunit of the yeast CP (Cdc68/Pob3)-FACT complex. Genes Dev 14, 1196-1208.
And I DID get the PDFs downloaded from these two references to import correctly:
Mosley, A.L., Pattenden, S.G., Carey, M., Venkatesh, S., Gilmore, J.M., Florens, L., Workman, J.L., and Washburn, M.P. (2009). Rtr1 Is a CTD Phosphatase that Regulates RNA Polymerase II during the Transition from Serine 5 to Serine 2 Phosphorylation. Molecular Cell 34, 168-178.
