I have read and understand GitHub's Guide to Filing a DMCA Notice. I am one of the authors of the Oracle Certified Associate Java Programmer Study Guide. It has come to my attention that a user is illegally hosting a copy of the book on github at: https://github.com/apoterenko/information-technology-ebooks/blob/master/%5BJAVA%5D%5BOCA%20Oracle%20Certified%20Associate%20Java%20SE%208%20Programmer%20I%20Study%20Guide%20Exam%201Z0-808%5D.pdf The book is on sale at Amazon at http://www.amazon.com/OCA-Certified-Associate-Programmer-1Z0-808/dp/1118957407 and the copyright is held by the publisher (Wiley). Looking through the repository, all of the other files in it appear to be copyrighted books as well. In order to keep any files online, the user should cite where they came from to show the books are in fact free PDFs. I went through the forks* as well and 30 of them contain our copyrighted book. The others were forked before our book was in the repository. The other forks still have copyrighted material, just not our book. The URLs of the forks containing an illegal copy of our book are: https://github.com/KingZhang/information-technology-ebooks https://github.com/MedianNguyen/information-technology-ebooks https://github.com/MrFcker/information-technology-ebooks https://github.com/RaviContributor/information-technology-ebooks https://github.com/alexandrzavalii/information-technology-ebooks https://github.com/alexxmde/information-technology-ebooks https://github.com/ayseyo/information-technology-ebooks https://github.com/danibuiza/information-technology-ebooks https://github.com/ezak4u/information-technology-ebooks https://github.com/fdelrieu/information-technology-ebooks https://github.com/fr-kshibata/information-technology-ebooks https://github.com/hemangsk/information-technology-ebooks https://github.com/idormenco/information-technology-ebooks https://github.com/kamlan/information-technology-ebooks https://github.com/lamlonghau/information-technology-ebooks https://github.com/louisnguyen1012/information-technology-ebooks https://github.com/m0cs/information-technology-ebooks https://github.com/maxifjaved/information-technology-ebooks https://github.com/morganwu277/information-technology-ebooks https://github.com/no-problemo/information-technology-ebooks https://github.com/oboff/information-technology-ebooks https://github.com/pccr10001/information-technology-ebooks https://github.com/rkmmanivannan/information-technology-ebooks https://github.com/ron825/information-technology-ebooks https://github.com/senseles/information-technology-ebooks https://github.com/txmns/information-technology-ebooks https://github.com/vaimr/information-technology-ebooks https://github.com/viinhpham/information-technology-ebooks https://github.com/yipyo/information-technology-ebooks https://github.com/zhuliangliang/information-technology-ebooks I have a good faith belief that use of the copyrighted materials described above on the infringing web pages is not authorized by the copyright owner, or its agent, or the law.

Thank you, [private] * I wrote a program to go through the forks; I didn't check 94 forks by hand to find the 30 matches.
