The scientific community has wide and efficient options to access electronic versions of scientific papers on Internet, starting from citations or from bibliographic or other scientific databases. What is not always clear is the fact that sometimes a particular article opens but sometimes not. In majority of cases the key problem is the IP address of the computer from which the user is asking for access.

This review summarizes the overall situation in availability of the electronic versions and some standing problems of further extension of access.
