We have installed KOha and are trying to use it for our library. We have some problems using MARC tags. We seek your help for the same. Are the tags below 010 required? If so does Koha recognize it? Also since we have not used Marc, we would like to know how do we enter data. For example, should the title be entered as 245 10 $a Computer Science OR Computer Science. Do we need to enter anything in the tag 000 or is it machine generated. --Trupti (koha user from India)
