Create new pages library in SharePoint 2013

You can save Pages library as a template with or without including the template but it won't be visible to create a new Pages library as SharePoint allows you to create only one Pages library on a site.

One alternative way to create another pages library is using powershell script detailed below:

$site = Get-SPSite http://site

$web = $site.OpenWeb("/")

$listTemplates = $site.GetCustomListTemplates($web)

$nonPublishingWeb = $site.OpenWeb("/TeamSite")

$nonPublishingWeb.Lists.Add("new list Instance name", "", $listTemplates["PagesTemplateName"])
