Cataloging maps

  1. 1. IST616: Information Resources: Organization and Access Professor Barbara H. Kwasnik Assignment 3: Providing Access to “Nonprint” Documents November 23, 2010
  2. 2.  Cartographic materials include all materials that represent the whole or part of the earth or any celestial body. Some examples include: maps, globes, atlas’, and electronic resources. For this presentation, I have chosen to focus only on the problems involved with cataloging maps.  Chapter 3 of the Anglo-American Cataloging Resource (AACR2R) has the standard information on how to catalog Cartographic Materials, but I have also used “Maps and Related Cartographic Materials,” by Andrew and Larsgaard which gives a more in-depth view of cataloging challenges involving these materials and how to solve them. Cartographic Materials
  3. 3. No one wanted to catalog the maps….
  4. 4. Why catalog maps?  maps are important sources of information  cataloging provides more access points than a geographic index, especially for maps covering more than one area  users are more likely to request (and use resources) that are cataloged  reduces wear (from browsing) Catalogers must be able to make numerous decisions when cataloging maps and they must understand the needs of the users. Access is one of the key factors to keep in mind when cataloging these valuable resources.
  5. 5. Maps can present many problems for Catalogers These may include:  Dating the map and/or determining what countries and boundaries would be on the map at different time periods  Lack of publishing details or obscure data  Who are the authors, or involved parties?  Accuracy of spatial data and/or drawn data (cartography)  Scale or scales  Languages used  Country or area names may have changed over time
  6. 6. Where does information come from when cataloging a map?  May be taken from any part of the map, not just from the title page or it’s verso as in a book  Information may be taken from the maps container or other accompanying materials
  7. 7. The Average library user  Looks for maps by location or subject, not by author
  8. 8. Chief Source of Information Where might the Chief Source of Information be found on a map? Many places… (Heiser,
  9. 9. 1. Title  Problem: Maps quite often provide more than one title from which to choose, a.k.a. Parallel titles 245 – Maps may have several titles. Take 245 title from actual map. When map is folded there might be an alternate title. This is called a panel title. 246; 1;i Panel title: $a
  10. 10. Choice of title  Problem: Sometimes it is difficult to decide what the main title of a map is, since it can be located anywhere on the “chief source”, and at times is printed more than once, in more than one location, and with different wording (grr!) (Heiser,
  11. 11. 2. Main Entry Problems  May be a personal name (e.g. the cartographer)  May be a corporate name – but only if the corporate body is responsible for more than just publication or distribution of the map (see AACR2 21.1B2, category f)  May be title (no primary responsible author/entity)  Author added entries (both personal and corporate names) are common  “Areas of difference between books and maps are many: primary identification of maps is with area rather than with authority, and maps are frequently published by a corporate (often a governmental) body. Determination of author, especially for foreign maps, is not always easy; even with U.S.-produced maps, authorship tends to be diffuse.” (Heiser,
  12. 12. Author Who is the Author or cartographer, or group, or corporation that produced the map?
  13. 13. Problems: Statements of Responsibility & Applying Main Entry  Maps may be the work of one person  Maps may be the work of a group of people working for a publishing agency or commercial company  Individuals may not be named (Heiser,
  14. 14. Corporate Author Examples of maps with corporate authors:
  15. 15. Map with Author Unknown
  16. 16. 4. Date of Publication Problem: How should a Map with no date be cataloged?
  17. 17. 5. Publisher and Place of Publication  Problems:  Publisher is not mentioned anywhere on the map  Distributor but not publisher is given
  18. 18. 6. Date of Publication  Problems:  No date of publication  Different dates on cover vs. legend
  19. 19. 7. Physical Description  Problems:  Margins are not included in the dimensions of the map  Neat lines, or the line that encloses the detail of the map may not be linear: may have irregular shapes 300 – The physical description consists of the number of items, color (if any), material (if other than paper), mounting (if any), and size.
  20. 20. Neat Line Explanation of map neat lines
  21. 21. Scale Problem: Map with two different scales
  22. 22. Mathematical data The main components of the mathematical data portion of the catalog record contain:  Scale  Projection  Coordinates
  23. 23. Scale Scale is given on maps in 3 basic formats:  Bar scale  Verbal scale  Representative fraction 034 – Coded cartographic material data – Data must also be entered in textual form in fie 255. Scale is always given in a representational fraction. If only the verbal scale is given, it should be translated. • Representative fraction – 1:6,842,880 • Verbal scale – 108 English Miles to 1 Inch
  24. 24. Bar Scale Example
  25. 25. Cataloging Problems with Scale  There is no scale on the map  The scale of a map changes across the face of the map (for instance, the scale is larger in the middle than along the edges)  More than one scale given
  26. 26. Map with No Scale Given
  27. 27. Problem: Scale changes The map scale changes with different projections, as seen in this map.
  28. 28. Multiple maps Problem: Should they be cataloged separately or as a set?
  29. 29. Geographic subject headings  Maps always have a geographic component to the subject(s)  Sometimes the geographic area is the only subject  Sometimes the geographic area is a subdivision of a topical subject  Problem: What if the country or geographic has changed since the map was created?

  31. 31. Problems cataloging Rare and Early Maps Cataloging early maps to create standard, consistent records for library catalogs...involves, like all library cataloging, not simply following a set of rules but also making a series of decisions.  Competing, and at times conflicting, factors that affect those decisions:  The amount of information content vs. the level of physical detail of the individual map.  The unique features of the individual map vs. matching it with the appropriate and specific cartobibliographic citation.  Application of the general rules for cartographic cataloging vs. special rules and considerations for early material.  Reconciling cataloging rules for early maps with those for rare books.  Reconciling the desire for meticulous and detailed citation records with the desire to get a larger number of existing items into the catalog.  Enhancing and clarifying the map cataloging rules, so as to ease and speed the work of the cataloger vs. allowing adequate flexibility and judgment where needed.

  32. 32. Troublesome units of measurement on old maps  Chain  Furlong  Heures de marche  League  Lieue  Miles (that aren’t statute)  Milliaria Germanica, Hispanica, etc  Pole  Toise (Scale on Old Maps Powerpt)
  33. 33. Conclusion  Maps are an important part of human history and heritage. It is crucial that they are preserved and maintained for others to utilize through the ages. Librarians help preserve our culture through cataloging and preserving maps and other cartographic materials for all to utilize.  Cataloging maps is a challenging job that makes these resources available and accessible to users. Because they are so different from traditional books, maps need special considerations and because of this, different fields in their MARC records that allow searching on such elements as: scale, geographical areas, types of maps, etc.
