⮚Carrier Type
A change in the carrier type (338 field) from online resource to another computer carrier and a change from another computer carrier to online resource are major changes and require a new description. All other changes in carrier type are minor. (CCM:16.4.1b)
Issue Variance. A serial's media or carrier type may vary from issue to issue. An example might be the USGS bulletin, where most issues are textual but some are maps or atlases, or a print journal with one issue each year in CD-ROM format. Treat these variations as minor. (CCM:16.4.1b)
