What's the best platform to publish documentation to internal users?

Solution 1:

I use http://www.dokuwiki.org/ because it is easy to set up, has a lot of features (my favourite is "Downloadable Code Blocks"), allows the use of ACLs and uses .txt files which don't depend on any Office/Office Version and are easy to back up.

It has everything you asked for except "if you don't have access to a doc, you don't see the link to that page/doc/folder"

If you are using single .doc(x) files at the moment, I would say it is totally worth the extra effort to move to dokuwiki.

Solution 2:

Have a look at Alfresco Share.

• It has access control by individual doc or by sets of docs, for users or groups.
• If you don't have access to a doc, you don't see the link to that page/doc/folder.
• It has a built-in editor for HTML
• It has version control
• You can see an online preview of documents, no need to download. This saves a lot of time over opening a PDF reader or an office software.
• Other collaboration features that can be easily enabled/disabled: wikis, calendars, issue trackers, data lists, blogs, forums.
• Your dashboard allows you to see all recent activity, for instance who recently uploaded what.
