<div class="articleParagraph">
<p>The <em>NLM Classification</em>, available online at <a href="//www.nlm.nih.gov/class/">
http://www.nlm.nih.gov/class/</a>, incorporates all additions and changes to the
schedules and index from May 2015 through April 2016. The <a href="//www.nlm.nih.gov/class/terms_cond.html">PDF version</a> will be updated with 2016 classification data by the end of May 2016.
</p>
<p>The QY (Clinical Pathology) and QZ (Pathology) schedules were the major area of focus for the 2016 edition.
</p>
<h2>Changes Made to the QY Schedule Name and Outline Headers
</h2>
<p>
The name of the QY schedule was changed from <em>Clinical Pathology</em> to <em>Clinical Laboratory Pathology</em><br /> <br />
</p>
<ul>
<li>QY 50-110 <em>Laboratory Animals. Laboratory Techniques</em> was changed to QY 50-60 <em>Laboratory Animals </em></li>
<li>QY 80-110 <em>Laboratory Techniques</em> was added </li>
<li>QY 120-350 <em>Diagnostic Tests</em> was changed to QY 118-350 <em>Specimen Analysis. Diagnostic Tests</em></li>
<li>QY 400-490 <em>Blood. Blood Chemistry</em> was changed to QY 400-490 <em>Hematologic Tests. Blood Chemical Analysis</em></li>
</ul>
<h2>Revisions to QY Class Number Captions and Notes for Better Scope Definition of the Number
</h2>
<p>For example:</p>
<ul>
<li>At QY 25, the caption was changed from <em>Laboratory manuals. Technique</em> to <em>Laboratory manuals (General)</em>. The note was changed from "Classify works on specific tests by type" to "Classify works on specific tests by type. Classify laboratory manuals on specific clinical techniques with the technique."</li>
<li>At QY 50, the note was changed from "Classify works on diseases of laboratory animals in SF 996.5; on vivisection as experimental surgery in WO 50; and on antivivisection in HV 4905-4959" to "Classify here works on animals used in research, testing, or teaching, including their anatomy and diseases. Classify general works on animals in QL."</li>
<li>At QY 58, the note was changed from "Cf. QY 25 Laboratory manuals" to "Classify works on experimental neoplasms in QZ 206."</li>
<li>At QY 110, the caption was changed from <em>Methods in medical mycology</em> to <em>Mycological techniques</em>.</li>
<li>At QY 120, the caption was changed from <em>Sputum</em> to <em>Sputum culture</em>.</li>
<li>At QY 160, the caption was changed from <em>Feces</em> to <em>Stool analysis</em>.</li>
<li>At QY 265, the caption was changed from <em>Agglutination, precipitation, flocculation, and complement fixation tests</em> to <em>Serologic tests (General)</em>.</li>
</ul>
<h2>Changes Made to the QZ Outline Headers</h2>
<ul>
<li>QZ 40-109 <em>Pathogenesis. Etiology</em> was changed to QZ 40-105 <em>Pathogenesis. Etiology</em></li>
<li>QZ 140-190 <em>Manifestations of Disease</em> was changed to QZ 140-190 <em>Pathologic Processes</em></li>
<li>QZ 200-380 <em>Neoplasms. Cysts</em> was changed to QZ 200-380 <em>Neoplasms</em></li>
<li>QZ 310-380 <em>Specific Types of Neoplasms</em> was added</li>
</ul>
<h2>Revisions to QZ Class Number Captions and Notes for Better Scope Definition of the Number
</h2>
<p>For example:</p>
<ul>
<li>At QZ 4, the note was changed from "Classify material on comparative pathology in QZ 33" to "Classify works on both the specialty and pathologic processes here. Classify works on the specialty only in QZ 21. Classify works on pathologic processes only in QZ 140. Classify material on comparative pathology in QZ 33."</li>
<li>At QZ 52, the caption was changed from <em>Genetic testing</em> to <em>Genetic services.</em></li>
<li>At QZ 140, the caption was changed from <em>General manifestations of disease</em> to <em>Pathologic processes (General).</em></li>
<li>At QZ 150, the caption was changed from <em>Local reactions to injury and disease</em> to <em>Inflammation.</em></li>
<li>At QZ 201, the note was changed from "Classify here popular works on all aspects of neoplasms" to "Classify here popular works on neoplasms in general. Classify popular works on neoplasms by site in the appropriate schedule."</li>
<li>At QZ 206, the caption was changed from <em>Research (General)</em> to <em>Research (General). Experimental neoplasms.</em> The note was changed from "Classify works on specific topics by subject, e.g., on experimental work on the etiology of neoplasms in QZ 202" to "Classify here all works on experimental neoplasms regardless of type or site."</li>
</ul>
<h2>
Changes to Other Class Schedules
</h2>
<p>For example:</p>
<ul>
<li>At QS 26, the note was changed from "Classify catalogs here" to "Classify catalogs here. Classify here all works on physical anatomic models even if used for educational purposes. Classify digital anatomic models in QS 26.5. Classify works on use of anatomic models for special subjects by subject."</li>
<li>At WC 160, the note was added: "Classify works on syphilis serodiagnosis in QY 275."</li>
<li>At WH 250, the note was deleted: "Classify works on histology and pathology of leukemia in QZ 350."</li>
<li>At WI 950, the note was added: "Classify works on hernias in general in QZ 140."</li>
<li><em>Surveys</em> was added to the caption of form number 16 in most schedules.</li>
<li>The form number for individual museums and exhibitions in each schedule now allows for Table G breakdown. No additional numbers for "Not Table G" were added. Form number 1 for societies and organizations now allows for Table G breakdown. No additional numbers for "Not Table G" were added.</li>
<li>NOTE: The MeSH trees for Mental Disorders (F03) underwent major changes in 2016. The class numbers and corresponding index terms will be reevaluated with the 2017 edition of the NLM Classification. </li>
</ul>
<h2><a href="//www.nlm.nih.gov/class/newclasses.html">Class Numbers Added and Canceled</a></h2>
<p>Fifty-eight (58) new class numbers were added. Eight (8) class numbers were canceled. The form numbers for Tables. Statistics. Surveys in the schedules now permit use of Table G to allow geographic breakdowns, so new numbers for "Not Table G" were added to many of the schedules.

<p><strong>Modifications</strong>:<br />
Numerous main index entries and cross references were modified to reflect changes in the MeSH vocabulary.</p>
<p>
For example:
</p>
<ul>
<li><em>Black Pepper</em> was deleted as a main heading and made a cross reference to <em>Piper nigrum</em>.</li>
<li><em>Day Care</em> was changed to <em>Day Care, Medical</em>.</li>
<li><em>Delirium, Dementia, Amnestic, Cognitive Disorders</em> was changed to <em>Neurocognitive Disorders</em>.</li>
<li><em>Origin of Life</em>, formerly a cross reference to <em>Biogenesis</em>, is now a main index heading.</li>
</ul>
<p><strong>Deletions</strong>:</p>
<ul>
<li>Seventy-eight (78) index entries were deleted.</li>
</ul>
