The textbook Diffeology is distributed by the AMS in the series Mathematical Surveys and Monographs. Starting April 22, 2013. According to an agreement with the AMS, the manuscript is no more available for download. Now, if you are a student and want a copy of the manuscript for your private use: send me an email and I’ will see what we can do. Since the book is now published, I opened a Blog on diffeology, to put there new exercises, remarks, errata etc.http://www.ams.org/bookstore-getitem/item=SURV-185mailto:piz@math.huji.ac.il?subject=Diffeology%20PDFhttp://www.ams.org/bookstore-getitem/item=SURV-185The%20Blog/The%20Blog.htmlhttp://math.huji.ac.il/~piz/documents/DBlog-Errata.pdfshapeimage_1_link_1shapeimage_1_link_2shapeimage_1_link_3shapeimage_1_link_4
