In theory the 1st indicator dictates the protocol used and 4 =HTTP. However, in all examples on http://www.loc.gov/marc/bibliographic/bd856.html, despite the indicator being used, the protocol part of the URI it is then repeated in the $u field.

You can put ‘7’ in the 1st indicator, then use subfield $2 to define other methods.

Since only ‘http’ is one of the preset protocols, not https, I guess in theory this means you should use something like

856 70 $uhttps://example.com$2https

I’d be pretty surprised if in practice people don’t just do:

856 40 $uhttps://example.com
