66 ]ourMl of Library Automation Vol. 2/2 June, 1969 APPENDIX I PRELIMINARY GUIDELINES FOR THE IMPLEMENTATION OF THE PROPOSED AMERICAN STANDARD FOR BIBLIOGRAPHIC INFORMATION INTERCHANGE ON MAGNETIC TAPE This Appendix is not part of the proposed Standard but is included to illustrate its application in one environment and recommended applica- tion in another. Part A of the Appendix contains general guidelines which apply to both Parts B and C. Part B contains the preliminary guidelines for the Library of Congress, National Library of Medicine, and National Agricultural Library implementation of the standard. Part C contains the proposed preliminary Committee on Scientific and Technical Informa- tion ( COSATI) guidelines for the implementation of the standard. A. GENERAL 1. Labels Volume header and file header labels are required and will con- form to USAS Proposed Standard X.3/552 Magnetic Tape Labels and File Structure. 2. Character Codes A code for a diacritical will always be recorded before the code for the alphabetic character which it modifies. 2.1 Character Definitions 2.1.1 Delimiter. The delimiter will consist of the "unit separator" (ASCII character 1/15). 2.1.2 Field TermiMtor. The field terminator will consist of the "record separator" (ASCII character 1/14). 2.1.3 Record TermiMtor. The record terminator will con- sist of the "group separator" (ASCII character 1/13). . 2.1.4 Padding Character. The padding character will consist of the "space" (ASCII character 2/ 0). 2.2 Ba.sic Character Set The basic character set will consist of the characters in columns 2, 3, 6 and 7 of the Standard Code as defined in USAS X3.4-1967 Code for Information Interchange, p. 6. This basic character set is included as part of the illustra- tion on p . 82 of this Appendix, columns 2, 3, 6 and 7. 3.

Delimiter and Data Element Identifier The delimiter will consist of the unit separator. The data ele- ment identifier will consist of one basic character. A delimiter will precede each data element identifier which in turn precedes each data element that it identifies. The first data element in each variable field will always be preceded by a delimiter and a data element identifier (even though there is only one data element in the field). 3. Indicat01' Two indicators will be used as the first two data elements in each variable data field. Each indicator will consist of one basic char- acter. H an indicator is not used, it will be set to blank (ASCII character 2/0) . No indicators are used in the control fields. 4.

Extended ASCII Character Set for Roman Alphabet and Rcnnan- ized Non-Roman Alphabets 8.1 Scope A library character set for the roman alphabet and roman- ized non-roman alphabets necessitates a larger number of characters than are provided for in the 7 -bit American Standard Code for Information Interchange (ASCII) . In addition, many libraries only have a 6-bit capability. There- fore, it was necessary to develop a character set which would meet all of the following requirements: (a) leave the 7 -bit standard (ASCII) intact, (b) expand the 7-bit standard to include an 8th bit to provide additional chamcters, (c) provide a shift mechanism which would make it possible to use all of the characters defined in the 8-bit set in the 6-bit environment. This section describes such a character set. 8.2 Criteria Governing Selection of Characters 8.2.1 Frequency of occurrence of character 8.2.2 Degree of necessity in expressing character when it occurred 8.2.3 Possibility of substituting one character for another or of expressing a character by writing it out •TaKI in the 800'• aro used for series added entries traced differently from the series rtatement. With the exception that no aecond indicators are used in the SOO's, tho indicators and data element ldentiBen are tile same as those used with the 400' s. Appendix I 81 8.3 Digital Codes The correlation of the character set to digital form code is based upon the ASCII (American Standard Code for In- formation Interchange) Standard. In conformance with the design considerations of ASCII ( 7 -bit code), the char- acter set is also correlated to an 8-bit code and a 6-bit code. The basic digital form code for the character set is the 8-bit code (see Figure 1 ) . 8.3.1 The 8-bit code is an extended form of the standard 7-bit ASCII. Some of the standard ASCII charac- ters such as the braces or the backwards slash are not proposed for the character set. However, no characters will be substituted for these code posi- tions. Other characters such as diacritical marks will be left in their standard position (unused) and duplicated in another portion of the code set reserved for special characters and diacriticals. 8.3.2 The 7 -bit code will be derived from the 8-bit code by removing the 8th bit. Those characters which previously had a 0 in the 8th bit will be considered part of the standard 7 -bit ASCII set. Those with a 1 in the 8th bit will be considered part of the non- standard set. A SO (shift out) control character will be used to go from the standard set to the non-standard. The code will stay in the non- standard mode until a SI (shift in) control char- acter is reached. 7-bit 8-bit SI I USASCII I ~I'--------'-;8-th_b_i_t _-_0__JI SO (special characters ~I :'8th bit ,. 1 I and diacriticals) : ~-----------------~---------~ 8.3.3 The 6-bit code will be derived by removing the 6th bit and the 8th bit. The 8-bit code set will be divided into 4 sets as follows: Columns 2, 3, 6 & 7 = Standard Set (referred to as the "basic set" in the Proposed Standard for a Format for Bibliographic Information Interchange, p. 56 and in paragraph A.2 of this Appendix) Fig. 1.

The presence of one of these codes will indicate that the next character is in one of the appropriate non-standard set. The code will then be automatically shifted back to the standard set. C.
