Map Collections and the Internet:
Some Ideas about Various Online Map Services, Based on the ETH Map Collection in Zürich

MAP COLLECTIONS ON THE INTERNET – WHY?

The Internet enables a map collection to be easily available to the general public. There are three different categories of information that can be provided:

  1. General information about the map collection (e.g. opening hours, terms and conditions, user support, workspaces)

  2. Search tools for maps, such as the library OPAC, index sheets for map series, map catalogues on the Internet

  3. Access to in-house and external digital products such as a digital map archive, thematic virtual map libraries, links to gazetteers, links to maps, bibliographies, courses and tutorials.

The Internet allows worldwide usage of map libraries. It is well suited for public relations and therefore important for today’s map libraries.

How can we develop and maintain a Web site? Usually there is no Webmaster available for map librarians. We have to do the work ourselves, including:

The map librarians have to learn how to create web sites using HTML. They have to learn how to navigate efficiently on the Web to find useful links for their own Web site. In addition, it is helpful to be creative using graphics in developing Web sites. This means more work and additional training and education.

On the other hand, we can profit from the work of our colleagues, for example by copying their index sheets or lists, selecting links from their Web sites or by consulting them. Communication between colleagues is helpful in developing and maintaining a useful Web site. The ETH-Bibliothek map site can illustrate some of the possible map services on the Internet.

HOW TO FIND THE HOMEPAGE OF THE MAP COLLECTION

The site can be located by:

THE HOMEPAGE OF THE MAP COLLECTION3

The homepage introduces the services and the collections.

The services and collections can be divided into three levels:

  1. Information

  2. Search tools

  3. Electronic products

Level 1: Information

a) Information about the Map Collection and how to Use it:

This lists available maps, people to contact, address, opening hours, terms and conditions, available workspace.

A link takes you to examples of digital maps covering our subject area.4

b) How to Use the Catalogue5

The catalog help offers the following facilities:

Level 2: Online Catalog and Search Tools

Maps can be searched in:

  1. Library online catalog (NEBIS-WebOPAC),
  2. an index sheet of the map series,
  3. CD-ROM and GIS data holding lists ,
  4. Internet search tool such as the World of Maps.

a) Online Catalog NEBIS (Network of Libraries)6

NEBIS comprises over 60 libraries. It contains holdings of the map series and atlases as well as the monographs in the ETH map collection. In NEBIS there are 40,000 records representing 300,000 maps.

b) The Indexes of Map Series7

Sheets of the map series are not recorded in NEBIS-WebOPAC. To find specific map sheets you have to go to the index of a map series. Once a map series is displayed, you can click on the index map to select the desired sheet number, and you can see a list of sheets with different editions. Wolfgang Crom (Berlin) presented this idea on a workshop in January 1999, which is easy to reproduce and also convenient for small map collections (see also Crom, 1999).

For a map collection with large holdings of map series it is recommended to use the professional software product TOPORAMA. It is user-friendly and has the map serial control function. TOPORAMA works with the software ArcView and requires an Internet map server from ESRI.


TOPORAMA: An integrated, interactive search net for map sheets worldwide. By clicking on an area of the index the desired map sheet can be obtained.

c) CD-ROMs8

The Web site contains a list of over 100 CD-ROMs with digital maps, spatial data and GIS products. They can be viewed on three large screen workstations in the map library. Examples:

d) The World of Maps Search for Maps and Mapping on the Internet9

The World of Maps is an extensive link collection for maps, spatial data, map catalogues and cartographic information.

It contains a geographical and a thematic map catalogue with metadata and digital maps, and numerous links to Web pages in cartography and map librarianship:

Level 3: Online Products

a) Digital Map Archive10

The digital map archive shows examples of the map holdings in digital form on the Internet.

This was created to be a map catalogue with image information. By zooming you can see a larger scale of map displayed with more cartographic and bibliographic details.

b) Registers of Local Places11

Registers of local places on the Internet are useful and popular sources.


Figure :

A „World Gazetteer“ is compiled from the index of Bartholomew Times Atlas, containing more than 100,000 names worldwide and searchable by name, country, co-ordinates, etc.

We plan to connect the World Gazetteer to TOPORAMA index sheets. From the index sheet it is easy to select a local place to get to the right map sheet.

c) Map Bibliographies12

The Web site was composed for the „Groupe des Cartothécaires de LIBER“ containing extensive multilingual bibliographies in map librarianship, map history and GIS/cartography, and important gateways for map curatorship.

d) Tutorials and Reference Sources13

This is a collection of links to free educational programs and reference sources in cartography, GIS, geography and geo-sciences.

e) Who is Who in Map Librarianship14

„Who is Who in Map Librarianship“ contains useful information about map librarians and their special fields of knowledge, serving as a guide to find help for any particular problem on a personal level. A valuable tool, organized by country and subject in order to find the relevant person.

f) Virtual Library Eduard Imhof History of Cartography on Internet15

„Virtual Library Eduard Imhof“ is created from original documents of the famous cartographer. This virtual library, is an interesting product making our archival material accessible world-wide, containing over 50 web sites with close to 200 pictures divided in 11 chapters, a biographical section and a reference list of the original resource. This is a valuable Web site both for historians in cartography and the general public.

CONCLUSION

The Map Collection on Internet is an opportunity with many possibilities:

It is a broad and demanding field and a challenge for our profession!
