Hello, thanks a lot for your response. I tried to test it but I think I didn't understand how to use it (I'm a beginner).

I would like to merge two datasets (variables: title, date, publisher). The problems is, that strings (tiltes of a book), that are not absolutely the same sould be merged/matched. - Does it make sense to use nearmrg for this? - In which way are strings merged/matched? - What would you recommend me?Some time ago I wrote a program to help a clerical do this rapidly. The program finds up to 5 likely matches, and lets the operator select the best match. I used it once to go through a few thousand journal article matches but it hasn't been used since. There is documentation at: http://www.nber.org/imatch and I would be interested in having a few more users. It is interactive, but it isn't a GUI program - it runs from the command line and the operator makes selections with the keyboard. Note that most commercial code to do matching is oriented towards address matching, and won't be particularly adept at author/title matching.
