A hard-copy of Keys to The Asteraceae of Wisconsin is available via a PDF file (500K). Having the document bound into a booklet with a spiral binding and goldenrod yellow covers (ca. $2.35 at a local copy shop) makes it much easier to use. Note that due to potential copyright violations the illustrations of composite morphology (Appendix A) and the phylogenies (Appendix B) are excluded from this PDF file. Thanks to Merel Black, the Keys are also available on-line via the UW-Stevens Point web-site, where each species is linked to pictures, a distribution map, and other information..
