Рядок 1:		Рядок 1:
		+	256 ELECTRONIC LOCATION AND ACCESS
		+	Field Definition
		+	This field contains the information required to locate the electronic item described by the
		+	bibliographic record. The information identifies the electronic location containing the item or from
		+	which it is available. It also contains information to retrieve the item by the access method identified
		+	in the first indicator position. The information contained in this field is sufficient to allow for the
		+	electronic transfer of a file, subscription to an electronic journal, or logon to an electronic resource. In
		+	some cases, only unique data elements are recorded which allow the user to access a locator table on a
		+	remote host containing the remaining information needed to access the item.
		+	Occurrence
		+	Optional. Repeatable when the location data elements vary (subfields $a, $b, $d) and when more than
		+	one access method may be used. It is also repeatable whenever the electronic filename varies
		+	(subfield $f), except when a single intellectual item is divided into different parts for online storage or
		+	retrieval.
		+	Indicators
		+	Indicator 1: Access Method
		+	# No information provided
		+	0 Email
		+	1 FTP
		+	2 Remote login (Telnet)
		+	3 Dial-up
		+	4 HTTP
		+	7 Method specified in subfield $y
		+	Indicator 2: Blank (not defined)
		+
		+	Subfields
		+	$a
		+	Host name
		+	Repeatable.
		+	$b Access number
		+	The access number associated with a host. It can contain the Internet Protocol (IP) numeric
		+	address if the item is an Internet resource, or a telephone number if dial-up access is provided
		+	through a telephone line. This data may change frequently and may be generated by the system,
		+	rather than statically stored. Subfield $b may be repeated if all the other information in the field
		+	applies. A telephone number is recorded as follows: [country code]-[area code]-[telephone
		+	number]. Example: 49-69-15251140 (a number in Frankfurt, Germany); 1-202-7076237 (a
		+	number in the U.S., Washington, D.C.). If an extension is applicable, include it after the
		+	telephone number preceded by ‘x’. Example: 1-703-3589800x515 (telephone number with
		+	extension). Repeatable.
		+	$c
		+	Compression information
		+	Repeatable.
		+	$d Path
		+	Repeatable.
		+	$e Date and Hour of Consultation and Access
		+	The time, in the form YYYYMMDDHHMM, at which the electronic item was last accessed.
		+	Not repeatable.
		+	$f Electronic name
		+	The electronic name of a file as it exists in the directory/subdirectory indicated in subfield $d on
		+	the host identified in subfield $a. Subfield $f may be repeated if a single logical file has been
		+	divided into parts and stored under different names. In this case, the separate parts should
		+	constitute a single bibliographic item. In all other cases, a file that may be retrieved under
		+	different filenames contains multiple occurrences of field 256, each with its corresponding
		+	electronic name in subfield $f. A filename may include wildcard characters (e.g., ‘*’ or ‘?’) if
		+	applicable, with a note in subfield $z explaining how files are named. NOTE: Filenames may be
		+	case-sensitive for some systems. This subfield may also contain the name of the electronic
		+	publication or conference. Repeatable.
		+	$h Processor of request
		+	The username, or processor of the request; generally the data which precedes the at sign ( ‘@’) in
		+	the host address. Not repeatable.
		+	$i Instruction
		+	An instruction or command needed for the remote host to process a request. Repeatable.
		+	$j Bits per second
		+	The lowest and highest number of bits (binary units) of data that can be transmitted per second
		+	when connected to a host. The syntax for recording the number of bits per second (BPS) should
		+	be: [Lowest BPS]-[Highest BPS]. If only lowest given: [Lowest BPS]-. If only highest given: -
		+	[Highest BPS]. Not repeatable.
		+	$k Password
		+	Used to record general-use passwords, and should not contain passwords requiring security. Not
		+	repeatable.
		+	$l
		+	Logon/login
		+
		+	General-use logon/login strings which do not require special security. Not repeatable.
		+	$m Contact for access assistance
		+	Repeatable.
		+	$n Name of location of host in subfield $a.
		+	Not repeatable.
		+	$o Operating system
		+	For information, the operating system used by the host specified in subfield $a is indicated in this
		+	subfield. Not repeatable.
		+	$p Port
		+	The portion of the address that identifies a process or service in the host. Not repeatable.
		+	$q Electronic Format Type
		+	Contains an identification of the electronic format type, whic h determines how data are
		+	transferred through a network. Usually, a text file can be transferred as character data which
		+	generally restricts the text to characters in the ASCII (American National Standard Code for
		+	Information Interchange) character set (i.e., the basic Latin alphabet, digits 0-9, a few special
		+	characters, and most punctuation marks). Text files with characters outside of the ASCII set, or
		+	non-textual data (e.g., computer programs, image data) must be transferred using another file
		+	transfer mode, usually binary mode. Electronic format type may be taken from lists such as
		+	registered Internet Media types (MIME types). Not repeatable.
		+	$r Settings
		+	The settings used for transferring data. Included in settings are:
		+	1) Number Data Bits (the number of bits per character);
		+	2) Number Stop Bits (the number of bits to signal the end of a byte); and
		+	3) Parity (the parity checking technique used). The syntax of these elements is:
		+	[Parity]-[Number of Data Bits]-[Number of Stop Bits]. If only the parity is given, the other
		+	elements of settings and their related hyphens are omitted (i.e., [Parity]). If one of the other two
		+	elements is given, the hyphen for the missing element is recorded in its proper position (i.e.,
		+	[Parity]--[Number of Stop Bits] or [Parity]-[Number of Data Bits]-). The values for parity are: O
		+	(Odd), E (Even), N (None), S (Space), and M (Mark). Not repeatable.
		+	$s File size
		+	The size of the file as stored under the filename indicated in subfield $f. It is generally expressed
		+	in terms of 8-bit bytes (octets). It may be repeated in cases where the filename is repeated and
		+	directly follows the subfield $f to which it applies. This information is not given for journals,
		+	since field 256 relates to the entire title, not to particular issues. Repeatable.
		+	$t Terminal emulation
		+	Repeatable.
		+	$u Uniform Resource Identifier
		+	The URI, which provides standard syntax for locating an object using existing Internet protocols.
		+	Field 256 is structured to allow for the creation of a URL from the concatenation of other
		+	separate 256 subfields. Subfield $u may be used instead of those separate subfields or in addition
		+	to them. The field is repeated if more than one URL needs to be recorded.
		+	Not repeatable
		+	$v Hours access method available
		+	The hours that access to an electronic resource is available at the location indicated in this field.
		+	Repeatable
		+
		+	$w Record control number
		+	Repeatable.
		+	$x Non-public note
		+	Repeatable.
		+	$y Access method
		+	The access method when the first indicator position contains value 7 (Method specified in
		+	subfield $y). This subfield may include access methods other than the main TCP/IP protocols
		+	specified in the first indicator. The data in this subfield corresponds with the access schemes
		+	specified in Uniform Resource Locators (URL) (RFC 1738), a product of the Uniform Resource
		+	Identifiers Working Group of the IETF. The Internet Assigned Numbers Authority (IANA)
		+	maintains a registry of URL schemes and defines the syntax and use of new schemes. Not
		+	repeatable.
		+	$z Public note
		+	Repeatable.
		+	$2 Link text
		+	Used for display in place of the URL in subfield $u (Uniform Resource Identifier). When
		+	subfield $2 is present, applications should use the contents of it as the link instead of subfield $u
		+	linking to the destination in subfield $u. Repeatable.
		+	Examples
		+	EX 1
		+	256 4#$uhttp://purl.pt/441
