It has been 2-3 years since frames were introduced to browsers and people have had hard times in using them and new problems are here too. I hope you will not find those in WebEc. Frames have been an option in WebEc through all these years, but now I have changed to them, since most of the browsers handle them 'well'. If you bump into a dead link in WebEc you can always send me a note. When I don't find specific servers while going through the links I give them some mercy and postpone their removal of the server to the next update.
Sites are sometimes temporarily down.
I don't remember. I wonder why I wrote this long this time. The search page is lighter to browse than before. The journals -page is divided into two parts both having just one column, because two columns do not look right with frames and the file was too big. A search form can be found on each WebEc-page.
