Ferris notes that it has been criticized for being too general to encompass the special skills that set catalogers apart from other library and information professionals. As stated by Tavani, a code of ethics for catalogers can "inspire, guide, educate, and discipline" (as cited in Bair, 2005, p. 22). Bair suggests that an effective code of ethics for catalogers should be aspirational and also "discuss specific conduct and actions in order to serve as a guide in actual situations". Bair has also laid out the beginnings for a formal code of cataloging ethics in "Toward a Code of Ethics for Cataloging." Criticism Sanford Berman, former Head Cataloger of the Hennepin County Library in Minnetonka, Minnesota, has been a leading critic of biased headings in the Library of Congress Subject Headings. Berman's 1971 publication Prejudices and Antipathies: A Tract on the LC Subject Heads Concerning People (P&A) has sparked the movement to correct biased subject headings. In P&A, Berman listed 225 headings with proposed alterations, additions, or deletions and cross-references to "more accurately reflect the language used in addressing these topics, to rectify errors of bias, and to better guide librarians and readers to material of interest". Berman is well known for his "care packages," mailings containing clippings and other materials in support of changes to subject headings and against racism, sexism, homophobia, and governmental secrecy, among other areas for concern. In "Three Decades Since Prejudices and Antipathies: A Study of Changes in the Library of Congress Subject Headings," Knowlton examines ways in which the Library of Congress Subject Headings (LCSH) has changed by compiling a table of changes described in P&A, followed by the current status of headings in question. Knowlton states that his intent for this table is to "show how many of Berman's proposed changes have been implemented" and "which areas of bias are still prevalent in LCSH." In the discussion of Knowlton's findings, it is revealed that of the 225 headings suggested for change by Berman, only 88 (39%) have been changed exactly or very closely to his suggestions (p. 127). Another 54 (24%) of headings have been changed but only partially resolve Berman's objections, and "(which) may leave other objectionable wording intact or introduce a different shade of bias." 80 (36%) headings were not changed at all according to Berman's suggestions.
