I'm pretty new to PowerShell and try to collect the following data about every document library in a site-collection:

  1. Document Library Name
  2. Created Date
  3. Content Type

Are there any general improvements i could do to the code? Are there any other way of getting the name of the content type?

add-pssnapin microsoft.sharepoint.powershell -erroraction SilentlyContinue 

$siteURL = "https://contoso.com/sites/projects"
$site = Get-SPSite($siteURL)

foreach($web in $site.AllWebs) 
    foreach($list in $web.Lists)
        if($list.BaseType -eq "DocumentLibrary")
        $listName = $list.Title
        $listCreatedDate = $list.Created
        $listContentType = $list.ContentTypes
        $listContentTypeName = $listContentType.Name

        write-host "List name: $listName"
        write-host "List created: $listCreatedDate"
        write-host "List content type: $listContentTypeName"

    $list.ContentTypes returns a SPContentTypeCollection. If one of your document library contains more than one content type, $listContentType.Name will return $null. Also, if there are no content types, or if content types are not enabled, $listContentType will likely be $null – Jeff Freeman Oct 8 '14 at 17:23

You could utilize the following pattern to inventory SharePoint objects (converted example):

Get-SPSite $siteURL |
Select -ExpandProperty AllWebs |
Select -ExpandProperty Lists | Where { $_.BaseType -eq "DocumentLibrary" } |
Select Title, Created, ContentTypes

    Excellent! Clean and simple output – Christoffer Oct 10 '14 at 13:29
  • One thing i noticed is that while running the script in powershell, the select statement for ContentTypes is displayed correctly but while trying to export it to a csv file, it returns "Microsoft.SharePoint.SPContentTypeCollection" instead of the content type name. – Christoffer Oct 10 '14 at 13:58

Try below piece in your code.

if($list.BaseType -eq "DocumentLibrary")
 foreach ($ctype in $list.ContentTypes)  

        write-host "List name:" $list.Title
        write-host "List created:" $list.Created
        write-host "List content type:" $ctype.Name
