A lot of student textbooks these days seem to have heaps of additional supplementary material to go with the text, both for students and teachers, such as electronic versions, online test banks, solution manuals, quizes etc. My question concerns specifically the teacher solution manuals. From what i have gathered, a student can't simply go into a bookshop and purchase the teachers material, it seems that they must be specially ordered (am i correct?). If this is the case, does anybody know if the publishers are usually strict about who they sell to? (i.e. do they check for a recognized licence in teaching at an accredited institution?). The reason i ask is that while i am not a school teacher by any means, i do tutor kids doing highschool courses in physics, chemistry and maths, and i believe it would be very handy to have the solution manuals to some of their textbooks so i can efficiently check their answers, rather than having to go through each question and work it out myself, which can be very time consuming. Has anybody who is a teacher or otherwise tried to purchase such materials, and if so, how did they go about checking your credentials? Would it be possible for me to get hold of some of these texts? Im sure if i really wanted to get hold of them i could ask one of my old highschool teachers to look into it for me, but i'd prefer to get it myself if at all possible. I guess it does depend on the specific publisher in question, but any input is appreciated Thanks, Daniel.
