<p class="first">
<span class="initcap">S</span>tarting in July 2008 new search options were introduced in the Entrez <a href="//www.ncbi.nlm.nih.gov/sites/entrez?db=journals">Journals database</a>.

<h2>ISSN Type</h2>
<p>
Please be advised that NLM follows the practice of a single bibliographic record when cataloging serials (see <a href="//www.nlm.nih.gov/pubs/techbull/jf02/jf02_hybrid_journals.html"><em>Cataloging Changes for Serials Issued Simultaneously in Print and Online</em></a>). Information about all media versions of a journal are in one record, e.g., a serial published both in print and online would have both a print ISSN and an electronic ISSN in one NLM serial record. If the print version subsequently ceases for a journal that was being published both in print and online, then the print ISSN remains in the NLM serial record, and NLM adds a clarifying note to the 911 MARC field that can be viewed in LocatorPlus<span class="registered">&#174;</span>. Any Journals database searches including one of the following tagged search terms may be affected by this policy: print [is] or electronic [is]. Accurate and current data in the ISSN fields are dependent on the publisher providing the appropriate ISSN for a journal. </p>
<h2>Journal List Searching </h2>
<p>There are various ways to generate journal lists:</p>
<ol>
<li>
<!--1--> Choose from the Current Subsets menu available from the Journals database Limits (see <a href="#fig4">Figure 4</a>). Examples include PMC Journals, Currently Indexed in MEDLINE from electronic version, and Nursing journals.
<br /><br /></li>
<li>
<!--2-->
Search the Subject Terms from the link on the Journals homepage. Subject Terms are broad MeSH<span class="registered">&#174;</span>
headings assigned to indexed journals to give an overall indication of the scope of the journal. (See <a href="//www.nlm.nih.gov/pubs/techbull/ma06/ma06_journals.html"><em>New Search and Display Options Available in the Journals database</em></a>.) For example, after clicking on the Subject Terms link, then click on the entry for Acquired Immunodeficiency Syndrome. That retrieves all journals assigned that subject term. Set the Currently Indexed for MEDLINE Limit and rerun the search to restrict the resulting list to currently indexed titles.<br /><br />
</li>
<li>
<!--3--> Search the Journals database using the search box for a specific journal subset. (See <a href="#table1">Table 1</a>.)<br /><br />
<a name="table1" id="table1"></a>

<h2>Sort Options</h2>
<p>Two new sort options have been added (see <a href="#fig1">Figure 1</a>):</p>
<ul>
<li>Title Abbreviation</li>
<li>Place of Publication<br /><br /></li>
</ul>
<p>The default is to display a title match followed by journals in alphabetical order by serial title, ignoring initial articles (such as A, An, The).</p>

</a>
</div>
<br />
<h2>Journal Display</h2>
<p>The Full Display in the Journals database now has additional fields that correspond to many of the search options (see <a href="#fig2">Figure 2</a>). In particular, please note these fields:</p>
<ul>
<li>
<strong><img src="graphics/1.gif"
alt=""
title="" />Current Indexing Status</strong> - Explains whether the journal is currently being indexed or not.<br /><br />
When citations were or are chosen by a <a href="//www.nlm.nih.gov/bsd/difference/spec_col_arr.html">collaborator</a> to NLM, a statement is displayed to indicate the specific subject area covered by that collaborator; e.g., "Not currently indexed for MEDLINE. Only articles related to bioethics were indexed."<br /><br />
Note that we have the capability to restrict searches as follows:<br /><br />
<table width="600" border="0" cellspacing="0" cellpadding="3">
<tr>
<td>currentlyindexed</td>
<td>[or choose Currently Indexed in MEDLINE from Limits page]</td>
</tr>
<tr>
<td>notcurrentlyindexed</td>
</tr>
</table><br />
The "notcurrentlyindexed" search includes journals that were never indexed for MEDLINE, such as the journals that are cited only in GenBank.<br /><br /></li>
<li><img src="graphics/2.gif"
alt=""
title="" /><strong>Current Subset</strong> - Lists the subsets to which a journal belongs.<br /><br /></li>
<li><img src="graphics/3.gif"
alt=""
title="" />
<strong>Version Currently Indexed</strong> - Specifies whether NLM processes the journal for indexing from the print or electronic version. This information must be viewed in relation to the Current Indexing Status; if the title is no longer indexed, then the Version Currently Indexed indicates the version used when the title was last being indexed.<br /><br /></li>
<li><img src="graphics/4.gif"
alt=""
title="" /> <strong>PMC Availability</strong> - States the coverage of the title in PubMed Central and any embargo details, or indicates that the title is forthcoming in PubMed Central.<br /><br />
</li>
<li><img src="graphics/5.gif"
alt=""
title="" /><strong>Acid-Free</strong> - Contains a standard phrase to inform when the title has some or all issues printed on acid-free paper and there is a notice published in the journal to that effect.
<br />

<h2>Send Journal List to PubMed<span class="registered">&#174;</span></h2>
There are two ways to create a journal list in the Journals database and then automatically search for the journal citations from those journals in PubMed:<br /><br />
<ol>
<li>Build a PubMed search for selected, multiple journals:<br /><br />
a. Run a search in the Journals database and on the results page(s) click the check boxes to select the journals. <br /><br />
b. Select Search Box with OR from the Send to menu. <br /><br />
c. To add additional journals continue searching the Journals database and adding the journals to the Search Box using the Send to Search Box with OR feature.<br /><br />
d. When your list of journals is complete, click the Search PubMed button. The Details of the PubMed search will show all journal titles you selected while in the Journals database.<br /><br />
</li>
<li>Send the entire results of a Journals database search to PubMed (without using the check boxes):<br /><br />
a. Run a search in the Journals database. For example, choose Education as a Subject term (using the Subject terms link from the information bullets on the Journals database homepage). This will run a search in the Journals database. (If you want only currently indexed journals, then click on the Limits tab and set the limit for Currently Indexed in MEDLINE and run the search again.) The actual titles are displayed here in the Journals database.<br /><br />
b. Choose PubMed Links from the Display pull-down menu (see <a href="#fig3">Figure 3</a>). This sends the journal titles search to PubMed. History will show this search as:<br /><br />
<strong>PubMed Links</strong> for <strong>Journals</strong> (Search <strong>Education[st]</strong> Limits: <strong>Currently indexed in MEDLINE</strong>)<br /><br />
</li></ol>
<br /><br />

</a>
</div>
<br />
<h2>Limits Screen</h2>
<p>The Limits screen (see <a href="#fig4">Figure 4</a>) has been enhanced to provide options to restrict your journals search by Language of the journal and by journal subsets (Nursing Journals, Consumer Health Journals, Dental Journals, etc.).</p>
<div class="figure" style="width: 624px;">

<p>Remember the Journals database contains journals cited in various NCBI databases. While PubMed is the predominant database represented, other NCBI databases (notably GenBank) are the reason for certain journals being included in the Journals database. These new search options and display fields help to clarify the status of a journal.<!--<a href="//www.ncbi.nlm.nih.gov/books/bv.fcgi?rid=helppubmed.section.pubmedhelp.Other_Services_Inclu#pubmedhelp.Searching_for_journa">Journals database Help</a> has been updated to provide information about these new search options. Help also includes instructions on how to build a list of journals using the Send to Search Box feature.--></p>
