Check out http://www.citeulike.org/ Does pretty much what you are asking for. You put in the details of papers, and assign keyword tags. You can also look at other people's libraries and so on.

I have no objection to an employer doing the best they can to determine whether I am up to the job in question. What I find hugely frustrating are the types of tests used, particularly for programming roles. What I have found is that I am generally tested on my ability to remember the syntax of some specific language rather tham my ability to think logically about how to solve the types of problems that I will come up against. This seems to me ridiculous, as I will often switch between languages with subtle differences in syntax, so will often fail blind tests of this type. Also, I think there is a tendency among managers to become hung up on current trends among technology and be always looking for the next exciting new thing, rather than good solid people with experience and ability.
