MARC tag 550 and 710

After doing assessment today, I just like to share some points on use of MARC tage 550 and 710 for a serial entry:

I search "British Economic Society) and found the:

The economic journal : the quarterly journal of the Royal Economic Society.

In the MARC record:

 http://catalog.loc.gov/cgi-bin/Pwebrecon.cgi?v4=2&ti=1,2&SEQ=20120418230739&Search%5FArg=british%20economic%20society&Search%5FCode=GKEY%5E%2A&CNT=100&type=quick&PID=aquOy2cJ9Q5l_MbjqYn2fcm2_W&SID=1

550	__ |a Vols. for 1891-1902 issued by: British Economic Association; 1903- by: Royal Economic Society.
555	__ |a Vols. 1 (1891)-10 (1900). 1 v.; v. 11 (1901)-20 (1910). 1 v.; v. 21 (1911)-30 (1920). 1 v.; v. 31 (1921)-40 (1930). 1 v.; v. 91 (1981)-100 (1990). 1 v.

and two added entries is listed:

710	2_ |a British Economic Association.
710	2_ |a Royal Economic Society (Great Britain)

As some candidates who are doing serials cataloguing will experience change of publishers and it is good to note the use of MARC tag 550 to add the notes and create MARC tag 710 for added entry.

Some other good reference pointers from the folloing ppt maybe of interest to some readers:
