Subfield+examples


 * SUBFIELD EXAMPLES**

If you are not used to looking at MARC records, you may be confused by the different subfield delimiters. It is important to understand where the information in a subfield begins and also to be able to separate the subfield delimiter from the information there. Here is a brief discussion of definitions: http://lili.org/forlibs/ce/able/course8/06terms2.htm.


 * Note that many of the online catalogs do not indicate the subfield code a -- but the first entry in the field is always subfield code a unless otherwise indicated: 245 $a, for example**

While we are looking at things, these records are all for the same book. Note the difference in the summary notes (520 $a) and also the subject headings (650 $a or 651 $a). For example, AMICUS doesn't use Harry Potter as a subject at all and the horrible SchoolCat record doesn't have any subject headings at all -- well, except for the 690 which is a local term -- (and, should have been in the 655 field anyway).
