1.Say that I put together informatin (for example animal species heart pulse)from various sources, including web. And publish that on web. All correctly referenced.

2.Writing my gradution thesis, that was all ok,without asking original authors, have no idea is there any law about that, everybody does it like that.

3.Ok the graduation thesis was on paper , published in faculty library and national library, have no idea what is different if I publish something on web.

4.Was 2 allowed as I was a student, surely not, all scietific comunity does it like that, so publishing some scientific contece on web under same rules shouldn't be a prob, or would be ?
