if((Get-PSSnapin | Where {$_.Name -eq "Microsoft.SharePoint.PowerShell"}) -eq $null) {          
  Add-PSSnapin "Microsoft.SharePoint.PowerShell"
}
function CreateLibrary
{
    param ($LibName)
    try
    {
        $spListCollection  = $OpenWeb.Lists 
        $spLibrary  = $spListCollection.TryGetList($LibName)
        if($spLibrary -ne $null) {
            Write-Host  -f Yellow "Library $LibraryName already exists in the site"
        }
        else
        {      
            $spListCollection.Add($LibName, "", $listTemplate)
            $spLibrary  = $OpenWeb.GetList($OpenWeb.ServerRelativeUrl+"/"+$LibName)
            Write-Host -f Green "Created Document Library $LibName"
        }
    }
    catch [System.Exception]
    {
 write-host -f red "Not set Likes Setting on " $_.Exception.ToString()
    }
}
$SiteURL = Read-Host -Prompt 'Enter Root Site URL and / @ end'
$OpenWeb = Get-SPWeb $SiteURL
$listTemplate = [Microsoft.SharePoint.SPListTemplateType]::DocumentLibrary
CreateLibrary -LibName "Department"

#enable Content Types

$spLibrary.Update();

# Enable Versioning with Limit

$spLibrary.Update();

#Order Columns

$FieldOrder = New-Object System.Collections.Specialized.StringCollection
$FieldOrder.Add("ContentType")
