In reading about bibliographic formats in chapter 4 of Chowdhury, I find it most confusing that for so long there has not been one common standard when it comes to exchanging information and records in a network of organizations. It seems to me, from the readings, that many attempts at creating a standard format for these records have been attempted, but there are still issues that arise when information needs to be exchanged. Even when the MARC format came about, the chapter states that while they adhere to the ISO 2709 record structure, USMARC, UKMARCm and other national MARC formats have some differences in terms of content designations. Eventually, most formats were consolidated into MARC 21, which uses a more widely accepted structure. I think from reading this chapter, I am much more impressed with the amount of decision that goes into creating a common language of tags and fields (just skimming through the MARC 21 tags and fields is mind boggling), although it still seems as though more study can be put forth into creating a true common standard.
