Cross reference should be simply Viscera. =Anatomy.= Why refer to Glands and not to Liver, the biggest gland in the body? Why to Chest and not to Lungs? Autopsy should not be referred to; that reference should come from Pathology. =Appendicitis.= This is a surgical disease and should be put under Surgery, Practice of, instead of Medicine, Practice of. =Contagion and contagious diseases.= Contagion and Infection seem to be confused. We are referred from Infection to Contagion as if they were synonymous terms. =Homeopathy.= "See also Medicine" should be used for polemical treatises only. These headings show a bias against Homeopathy which is common in some classifications. =Hygiene.= Has 54 "See alsos," most of which are fair but one-half of them could be omitted to the bettering and clearing of the list. =Hygiene, Public.= This is better on the whole than Hygiene (plain), more consistent and logical in their references and cross references, thus confirming our contention that it is from lack of medical and surgical knowledge that these lapses occur. =Medicine.= I should omit the following special headings, leaving only the general: Allopathy; Anatomy; Anæsthetics; Antiseptics; Autopsy; Bacteriology; Dentistry; Diagnosis; Histology; Homeopathy; Hospitals; Inoculation; Narcotics; Pathology; Pharmacy; Physiology; Stimulants; Surgery; Therapeutics; Vaccination. From =Medicine, Practice of=, I should omit all the surgical headings as follows: Appendicitis; Bones, Diseases; Cancer; Erysipelas; Eye, Diseases and Defects; Obstetrics; Surgery; Tumors. Dr. Wire recommended that a medical mind with suitable library training should have been consulted about these headings before a final printing. Miss Anna M. Monrad, of Yale university library, outlined the principles and scheme of subject headings for philology and literature applied in the catalog of Yale university library. SECOND SESSION (Friday, June 28, 8:15 p. m.) The second session of the Catalog section was held in the ballroom of the Chateau Laurier on the evening of Friday, June 28, Miss Thompson presiding. Mr. Keogh, Miss Van Valkenburgh and Miss Mann were appointed by the chairman as nominating committee. The first paper was by Miss ONO MARY IMHOFF of the Wisconsin legislative reference library, on CATALOGING IN LEGISLATIVE REFERENCE WORK The state which studies the laws and experience of other states and countries in order to bring to its own statute books the best features of each, combined with the results of original work, confronts a problem of no small dimensions. The mass of laws put forth by the forty-eight states of this country is so overwhelming that it is practically impossible for one man thoroughly to comprehend their merits and disadvantages. The legislative reference library, therefore, must be of service in helping to select that which is worthy of imitation, at the same time discarding the impractical features.
