The International Mathematical Olympiad (IMO) Shortlisted Problems. Before the IMO takes place the IMO Problem Selection Committee chooses a subset of the proposed problems of all countries (IMO LongList, ILL). This subset contains 20-30 problems and is called IMO ShortList (ISL). This ISL is used to select the 6 IMO problems.

Are there the IMO longlist problems (besides the ones in http://www.mathlinks.ro) with solutions? I do not want to spend time solving any problem and later found that there are available solutions somewhere. Thank you.
