MARC STANDARDS (Network Development and MARC Standards Office, Library of Congress) Guidelines for the Use of Field 856. First Indicator (Access Method).
The first indicator contains information about the access method to the resource and has values defined for Email, FTP, Remote login (Telnet), Dial-up, and HTTP. Access methods without defined values may contain a first indicator value 7 with the method indicated in subfield $2. Older records may contain value 7 and subfield $2 (with content http) if created before value 4 (HTTP) was defined. The list of indicator values and the values used in subfield $2 is specified in the URL standard (RFC1738) and maintained by the Internet Assigned Numbers Authority (IANA). A list of URI schemes is online at: For those access methods that have an indicator value defined (ftp, telnet, electronic mail), the URI is included in subfield $u with the appropriate indicator value recorded, even though it is redundant with the first element of the URI.
Value # (blank) (No information provided) may be used if only a URN is recorded in subfield $u.
