to the public. It will first be available to vendors to try out, but afterwards there will be a hybrid form of the system (MARC and BIBFRAME) until the data can be fully translated. Library digital collections often use simpler digital formats to store their metadata. XML-based schemata, particularly Dublin Core and MODS, are typical for bibliographic data about these collections. Transliteration Library items that are written in a foreign script are, in some cases, transliterated to the script of the catalog. In the United States and some other countries, catalogers typically use the ALA-LC romanization tables for this work. If this is not done, there would need to be separate catalogs for each script. Ethical issues Ferris maintains that catalogers, in using their judgment and specialized viewpoint, uphold the integrity of the catalog and also provide "added value" to the process of bibliographic control, resulting in added findability for a library's user community. This added value also has the power to harm, resulting in the denial of access to information. Mistakes and biases in cataloging records can "stigmatize groups of people with inaccurate or demeaning labels, and create the impression that certain points of view are more normal than others". Social responsibility in cataloging is the "fair and equitable access to relevant, appropriate, accurate, and uncensored information in a timely manner and free of bias". In order to act ethically and in a socially responsible manner, catalogers should be aware of how their judgments benefit or harm findability. They should be careful to not misuse or misrepresent information through inaccurate or minimal-level cataloging and to not purposely or inadvertently censor information. Bair states that it is the professional obligation of catalogers to supply thorough, accurate, high-quality surrogate records for databases and that catalogers also have an ethical obligation to "contribute to the fair and equitable access to information." Bair recommends that catalogers "actively participate in the development, reform, and fair application of cataloging rules, standards, and classifications, as well as information-storage and retrieval systems". As stated by Knowlton, access points "should be what a particular type of library patron would be most likely to search under -- regardless of the notion of universal bibliographic control." A formal code of ethics for catalogers does not exist, and thus catalogers often follow library or departmental policy to resolve conflicts in cataloging. While the American Library Association created a "Code of Ethics",
