 <title>Editorial: Helpful Reviews</title>
 <link>http://prl.aps.org/edannounce/PhysRevLett.100.170001</link>
 <description>We recently stated here that peer review is a source of great strength for APS journals, but did not discuss why. What are the elements of a helpful report? Who benefits from such a report, and how?</description>

 <title>Editorial: Successful Letters</title>
 <link>http://prl.aps.org/edannounce/PhysRevLett.100.100001</link>
 <description>Physicists borrowed the word &quot;quark&quot; from &lt;i&gt;Finnegans Wake&lt;/i&gt;, but James Joyce had no obvious connection to physics.  However, all scientists, including physicists, must know how to write.</description>

 <title>Essay: The Tau Lepton and Thirty Years of Changes in Elementary Particle Physics Research</title>
 <link>http://prl.aps.org/edannounce/PhysRevLett.100.070001</link>
 <description>Starting with the 1975 discovery of the tau lepton, I look back on the last three decades of change in the substance and style of experimental and theoretical research in elementary particle physics. I recount the major accomplishments of those decades and predict a bright future for particle physics in the next two decades. Turning to three problems, I lament the change in theoretical style and taste, I discuss the growth in the complexity, size, and cost of particle physics experiments, and I conclude with a pessimistic comment on the size of particle physics collaborations.</description>

 <title>Editorial: Peer Review per Physical Review</title>
 <link>http://prl.aps.org/edannounce/PhysRevLett.100.050001</link>
 <description>We editors often say, and also often hear, that the great strength of &lt;span style=&quot;font-style: italic&quot;&gt;Physical Review&lt;/span&gt; and &lt;span style=&quot;font-style: italic&quot;&gt;Physical Review Letters&lt;/span&gt; lies in the extensive peer review that submitted manuscripts receive. This widely held view is a natural topic for our discussion surrounding the 50th anniversary of &lt;span style=&quot;font-style: italic&quot;&gt;PRL&lt;/span&gt;.</description>

 <title>Essay: Physical Review Letters; Sam Goudsmit’s Vision</title>
 <link>http://prl.aps.org/edannounce/PhysRevLett.100.020001</link>
 <description>Sam Goudsmit implemented his vision of converting the Letters section of &lt;span class=&quot;italic&quot;&gt;Physical Review&lt;/span&gt; into a distinct journal fifty years ago. &lt;span class=&quot;italic&quot;&gt;Physical Review Letters&lt;/span&gt; was designed to publish “only papers that really deserve rapid communication.” The new journal became so successful with physicists throughout the world that &lt;span class=&quot;italic&quot;&gt;Physical Review Letters&lt;/span&gt; now publishes 3500 Letters per year. </description>

 <title>Editorial: Physical Review Letters at 50</title>
 <link>http://prl.aps.org/edannounce/PhysRevLett.100.010001</link>
 <description>During the course of the 50th year we will publish a series of Editorials on issues facing the journals as well as on scientific publishing. The first Editorial is more of an introduction to features and events we are planning for the year, and which we will announce frequently on this web site.</description>
