[Avodah] Rambam and RIF

[Allen Gerstl]

Dr. David Berger in the course of his paper, Judaism and General Culture in 
Medieval and Early Modern Times which is found in Judaism's Encounters with 
Other Cultures, J.J. Schacter (ed.), (Aronson: 1997) at p. 82, cites a 
letter from the Rambam to Joseph ben Judah apparently in answer to a request 
by the latter for wheather he should open a yeshivah and as to its 
curriculumn. Among other matters, he promotes the study of the RIF in that 
proposed school and then says:
                ... compare it [the RIF abbreviated Talmud] with the 
Composition [i.e. the Mishneh Torah]. IF YOU FIND A DISAGREEMENT, KNOW THAT 
CAREFUL STUDY OF THE TALMUD BROUGHT IT ABOUT, AND  **STUDY THE RELEVANT 
PASSAGE**. ... [emphasis mine]

Does anyone know of whether there is an expeditious way of pinpointing those 
halachot where the Rambam disagrees with the RIF so that one may implement 
the Rambam's suggestion to Joseph ben Judah.  I realize the if someone used 
the Rambam and compared each halacha to that of the RIF such could be found 
but my question is as to whether there is such a list in any source or 
whether there is a source that can be used to easily and expeditiously to 
create a list of such disagreements between the Rambam and the RIF so as to 
implement that particular suggestion of the Rambam to "study the relevant 
passage[s]".
