Display entries by current entry author? I have a blog section on my site and would like a "More posts by this author" list. How would I go about this, the logic is clear but the syntax to write for it is not forthcoming.
In order to display all other entries by an author except the current one, you will need to perform another step — either by filtering out the current entry from the query or adding a conditional.

{% set authorId = entry.author.id %}
{% set allEntryIds = craft.entries.section('blog').authorId(authorId).limit(null).ids() %}
{% set otherEntryIds = allEntryIds|without(entry.id) %}
{% set otherEntries = craft.entries.section('blog').id(otherEntryIds) %}

&lt;ul&gt;
    {% for entry in otherEntries %}
        &lt;li&gt;&lt;a href="{{ entry.url }}"&gt;{{ entry.title }}&lt;/a&gt;&lt;/li&gt;
    {% endfor %}
&lt;/ul&gt;


or

{% set authorId = entry.author.id %}
{% set authorEntries = craft.entries.section('blog').authorId(authorId).limit(null) %}
&lt;ul&gt;
    {% for authorEntry in authorEntries %}
        {% if not authorEntry.id == entry.id %}
            &lt;li&gt;&lt;a href="{{ entry.url }}"&gt;{{ entry.title }}&lt;/a&gt;&lt;/li&gt;
        {% endif %}
    {% endfor %}
&lt;/ul&gt;
