Cataloguing Cartographic Materials on CD-ROM:  Cataloguing Cartographic Materials on CD-ROM Karen Jensen McGill University Highly Recommended:  Highly Recommended Cartographic Materials: A Manual of Interpretation for AACR2, 2002 Revision / prepared by the Anglo-American Cataloguing Committee for Cartographic Materials, Elizabeth U. Mangan, editor. 2nd ed. Chicago: American Library Association, 2003. Three Types of Cartographic Electronic Resources::  Three Types of Cartographic Electronic Resources: Scanned images of maps Electronic atlases Geospatial data Scanned Image of a Map:  Scanned Image of a Map A map is a representation, normally to scale and on a flat medium, of a selection of material or features on the surface of the Earth. Scanning involves capturing images from hardcopy sources. Maps are usually scanned on large-format colour scanners. Scanned Image of a Map:  Scanned Image of a Map Part of: Bowles, Carington. “North America, and the West Indies ...” 1774? American Memory. Map Collections: 1500-2004. [] Electronic Atlas:  Electronic Atlas An atlas is a systematically arranged collection of maps. It is distinguished from other collections of maps primarily by the publisher’s or compiler’s intent that the work by used like a book and shelved in the form as issued. An electronic atlas may be the digital counterpart to a traditional paper atlas, or it may be interactive, allowing users to manipulate the data. Geospatial Data:  Geospatial Data “Geospatial data are information about the shape and location of objects on the Earth’s surface that can be manipulated in desktop mapping or in geographic information systems (GIS) programs (e.g., ArcView, ArcInfo, MapInfo, Intergraph) to perform geographic analysis and produce maps.” Geospatial Data:  Geospatial Data Vector data represent geographic features as x, y or x, y, z coordinates. Features are described as points, lines (or arcs), and polygons. Raster data use a cell- or pixel-based method of representing the Earth’s features, with each cell or pixel having a value. Map Created With Vector Data :  Map Created With Vector Data Part of: “Tennessee River and Interconnected Inland Waterway System.” Alabama Maps. Contemporary Map Index. [] Scanned Map (Raster Data):  Scanned Map (Raster Data) Part of: Desilver, Charles. “Canada East, Formerly Lower Canada with Inset of Nova Scotia and New Brunswick.” 1856. Alabama Maps. Historical Maps Archive. [] Satellite Image (Raster Data):  Satellite Image (Raster Data) Part of: “Ohio Flood.” RADARSAT International Image Gallery RADARSAT 1. [] Raster Data:  Raster Data Raster files store image information, such as scanned paper maps or aerial photographs. Also used for data captured by satellite and other airborne imaging systems. GIS Data Formats describes common formats for vector and raster data. Published vs. Commercial:  Published vs. Commercial “Published” electronic resource = available and/or accessible to the public. Includes commercially available packages, data, etc., or files that may be downloaded and/or accessed via the Internet. Non-commercial geospatial data are often distributed on CD-ROMs without any special packaging. Non-commercial Publications:  Non-commercial Publications 2003 American Library Association Annual Conference covered non-commercial publications. Electronic-Resource Cartographic Materials - The Basics by Grace Welch (University of Ottawa). Cataloging Electronic-Resources Cartographic Materials - The Basics by Mary Lynette Larsgaard (University of California, Santa Barbara). Available at What is a cartographic electronic resource?:  What is a cartographic electronic resource? Emphasis on cartographic material. Textual material is secondary and serves mainly to support and explain the cartographic content. Code the Leader/06 (Type of Record) character position “e” for Cartographic material. Guidelines:  Guidelines Guidelines for Distinguishing Cartographic Electronic Resources from other Electronic Resources, January 1998 (Revised December 2001) / Cataloging Policy and Support Office, Network Development and MARC Standards Office, Geography and Map Division, and Special Materials Cataloging Division, Library of Congress. ( Coding the Fixed Fields:  Coding the Fixed Fields LC adds an 008 for maps and an 007 for computer files. McGill also adds an 006 for computer files and an 007 for maps. A combination of the fixed fields labels this type of material “Digital Map” in our catalogue. MARC 21 Concise Format for Bibliographic Data ( 008--MAPS:  008--MAPS 18-21 - Relief is usually blank for No relief shown. 22-23 - Projection indicates the projection used in producing the item. 25 - Type of cartographic material indicates the type described in the bibliographic record. LC uses only “a” - Single map or “b” - Map series. 28 - Government publication indicates whether the item is published or produced by or for a government agency. 008--MAPS:  008--MAPS 29 - Form of item indicates the form of material for the item. s - Electronic 31 - Index indicates whether the item or accompanying material includes a location index or gazetteer. 0 - No index 1 - Index present 33-34 - Special format characteristics indicates the special format characteristics of the map. Usually give as blank. 006--Computer Files/Electronic Resources :  006--Computer Files/Electronic Resources 00 - Form of material is “m” - Computer file/Electronic resource 09 - Type of computer file is usually “c” for Representational or “m” for Combination. Representational = pictorial or graphic information that can be manipulated in conjunction with other types of files to produce graphic patterns that can be used to interpret and give meaning to the information. 11 - Government publication 007--Electronic Resource:  007--Electronic Resource 00 - Category of material is “c” - Electronic resource 01 - Specific material designation is “o” - Optical disc 03 - Color is a - One color b - Black-and-white c - Multicolored 04 - Dimensions is “g” - 4 3/4 in. or 12 cm. 05 - Sound is # - No sound (silent) a - Sound on medium 007--Map:  007--Map 00 - Category of material is “a” - Map 01 - Specific material designation: d - Atlas j - Map r - Remote-sensing image (An image produced by a recording device that is not in physical or intimate contact with the object under study. Remote-sensing devices include cameras, lasers, radiometers, scanners, radar systems, sonar, and scintillation counters used at a distance (as from aircraft, spacecraft, or ship)). 007--Map:  007--Map Note that a separate 007 exists specifically for remote-sensing images, but don’t use it for most electronic resources. 03 - Color a - One color c - Multicolored 007--Map:  007--Map 04 - Physical medium indicates the material out of which the item is made. Our policy is to code this with a fill character because digital maps do not exist on a physical medium. | - No attempt to code 007--Map:  007--Map 05 - Type of reproduction indicates whether the item is a facsimile or other type of reproduction. Do not treat raster images created by scanning as facsimiles. n - Not applicable 007--Map:  007--Map 06 - Production/reproduction details indicates the photographic technique used to produce the item. z - Other 07 - Positive/negative aspect indicates the positive/negative polarity of the photocopy or film. n - Not applicable General Material Designation:  General Material Designation GMD for digital maps. At McGill, we follow LC policy of using [electronic resource], so that the GMD matches the physical description of the record. LC never uses [cartographic material], and we wanted our records to match theirs. 034--Coded Cartographic Mathematical Data :  034--Coded Cartographic Mathematical Data Coded form of the cartographic mathematical data contained in field 255. 034:1 :|a a |b 100000 with 255: :|a Scale 1:100,000. 034:0 :|a a with 255: :|a Scale not given. 034:1 :|a a |b 253440 |d E0790000 |e E0860000 |f N0200000 |g N0120000 with 255: :|a Scale 1:253,440 |c (E 79°--E 86°/N 20°--N 12°). 043, 045:  043, 045 043--Geographic Area Code is not used for maps. 045--Time Period of Content is used by LC to represent the date of map situation, the date portrayed by the map. Date of situation is considered to be of almost equal importance to the geographic and subject content of the map, and is included as part of the item’s call number. 050--Library of Congress Call Number :  050--Library of Congress Call Number LC uses only the maps portion of the LC G Schedule for classification. The main entry cutter always appears after the date in the call number. Special Instructions and Tables of Subdivisions for Cartographic Materials ( 052--Geographic Classification :  052--Geographic Classification A code for the main geographic area and any applicable subareas associated with the item. The code is derived from the LC class G schedule by dropping the letter G. |b - Geographic classification subarea code. An alphanumeric code, assigned from expanded Cutter lists, that represents a subarea of the geographic area coded in subfield |a. Cutter numbers for places in the U.S. are published in Geographic Cutters by the Library of Congress. 255--Cartographic Mathematical Data:  255--Cartographic Mathematical Data Statement of scale, the statement of projection, and the statement of coordinates. Linear scales are shown on a map as: 1. representative fractions: 1:50,000; 1:63,360 2. verbal scales in the form of phrases stating map distance in relation to Earth distance: 1 inch to 1 mile; 2 cm. to 1 km. 3. graphic scales, usually a bar scale 255--Cartographic Mathematical Data:  255--Cartographic Mathematical Data For electronic resources, give the scale if the resource has a scale statement or if the scale is already recorded as part of the title. Otherwise, give Scale not given. If the main maps in a cartographic item are of more than one scale, give Scales differ. If all of the main maps in a cartographic item are of two scales, give both scales in separate scale statements. If there are more than two scales, give Scales differ. Examples of Graphic or Bar Scales:  Examples of Graphic or Bar Scales Often the left end of the bar is subdivided into smaller units to provide more precise estimation of distances. 255--Cartographic Mathematical Data:  255--Cartographic Mathematical Data Give the statement of projection if it is found on the item, its container, or accompanying printed material. Map projection is “any systematic arrangement of meridians and parallels, portraying the curved surface of the sphere upon a plane.” Give the statement of coordinates when the information is readily available. 256--Computer File Characteristics:  256--Computer File Characteristics Type and extent of resource. Characteristics of a computer file, such as the type of file, the number of records or statements. Add if considered important and not found elsewhere in the description. No longer seems to be used at LC for electronic cartographic resources. If adding this field, give Electronic data or Electronic data and programs. 256 relates to 516 (Type of computer file or data note), but neither are commonly used for electronic cartographic materials. 300--Physical Description :  300--Physical Description Recommended to give the extent of the cartographic item (number of physical units of atlases or globes, or the number of maps) on the physical carrier. Use conventional terminology to record the specific format of the physical carrier; use CD-ROM or DVD-ROM. If the resource has sound, give sd. If it displays in two or more colours, give col. For CD-ROMs, the dimensions are 4 ¾ in. 5xx--Notes:  5xx--Notes Make notes in the order given in AACR2, but give a particular note first if considered of primary importance. 500 Nature and scope of the item; include date of situation, relief, 538, data quality assessments, metadata descriptions. 538 System requirements. Make a note of the system requirements of the resource if the information is readily available. 546 Language. 5xx--Notes:  5xx--Notes 500 Source of title proper. This note is required for electronic resources. The chief source of information for cartographic electronic resources is the resource itself. For commercial publications on CD-ROM, usually give Title from disc label. 5xx--Notes:  5xx--Notes 516 Type of computer file or data note. A general descriptor that characterizes a file (e.g., text, computer program, numeric). Specific information such as the form or genre of textual material (e.g., biography, indexes) also may be included. Add if the nature of the item is not apparent from the rest of the description. 5xx--Notes:  5xx--Notes 530 - Additional Physical Form Available Note. Example: Also available in print version and online via the GLERL home page. 520 - Summary. Give a summary unless another part of the description provides enough information. 505 - Contents. 65x--Subjects:  65x--Subjects Currently no way to indicate a scanned map is in digital form. LC uses 653 (Index term - uncontrolled) Maps--Digital. Don’t use |v Databases. Digital mapping is for works ABOUT digital mapping, not for actual digital maps. Don’t use 650 Geographic information systems |v Maps.
