work, and having one place to go for help with these questions speeds the completion

of the task at hand.</p><p>People approach their tasks from two viewpoints—one of producing an NCBI website or
|
|
Bookshelf content, and one of producing content to be published outside of NCBI.
|
|
“The NCBI Style Guide” is geared toward helping people produce NCBI websites and
|
|
Bookshelf content by providing specific examples of uses typical to NCBI. There are
|
|
portions of “The NCBI Style Guide” that provide advice on technical writing in
|
|
general, as well as a list of other suggested style guides that may be helpful to
|
|
people producing content to be published elsewhere. Bear in mind that for content
|
|
published elsewhere, the suggestions for specific styles may not apply.</p><p>“The NCBI Style Guide” is basically divided into two main parts, General Writing
|
|
Skills and NCBI-specific Styles, to provide some assistance to people in both
|
|
groups.</p></div><div><h2>Contents</h2><div class="bktoc_all_cntnr top align_right" style="display:none"><ul class="inline_list_right"><li><a class="bktoc_all_exp" href="#">Expand All</a></li><li style="margin-left:.8em"><a class="bktoc_all_clps" href="#">Collapse All</a></li></ul></div><ul id="toc_tllNBK988_toc_A363" class="simple-list toc toc-toggle"><li class="half_rhythm" id="toc_itm_NBK988_toc_A363"><a class="toc-item" href="/books/n/styleguide/A363/">Preface</a></li><li class="half_rhythm" id="toc_itm_NBK988_toc_I_bxml"><a class="toc-item" href="/books/n/styleguide/I.bxml/">Part I.
