Books/Book chapters

Note: the books provided here are mostly for personal circulation, mainly for the socially and economically poor students, as the author of this website I am well aware that "personal circulation of electronic format" is against the copyright norms, however, I use this method owing to the "unequivocal educational value of these contents."

If still any publisher or author of the books provided below has objection or reservation against their book usage for educational purpose of the socially and economically downtrodden students community, please feel free to inform your concern in vigsaran@gmail.com.
