The selection of papers available is great. (Sorry, I haven't come back jet. Free bump for that. I don't have much time recently and still going through to what I might need.)
For Example: That's an invaluable service here for anyone just writing his Master/Bachelor thesis.
If I had only known you a view years sooner.
dont university libraries already give you access to thousands of journals?
Yes, if you have access to a university library they can get papers for you. But not everybody has easy access to such an institution.
I have access (through where I work) to most chemistry journals. If there is something you cannot access, I would be willing to try to get it.
