My research with Donald King shows journal articles are…
Widely read by scientists and students as a reliable source of information
Read for many reasons, including research, writing, teaching/learning, and current awareness
Highly valued and essential Most commonly found through library Increasingly read from library e-collection
![Page 3: Indexing of Tables and Figures: Scientists’ Reaction Carol Tenopir University of Tennessee ctenopir@utk.edu web.utk.edu/~tenopir](https://reader031.vdocuments.us/reader031/viewer/2022013012/56649f295503460f94c4338f/html5/thumbnails/3.jpg)
Scientists and other scholars must read more…
More articles are published every year Reading more to keep up with their field Peer reviewed journals are essential E-journal systems and search engines
provide access to more journals and articles quickly

Key Research Questions for Tables & Figures (T&F) Indexing
1. What do scientists currently do with T&F?
2. How might they use a T&F index?
3. How effective is T&F searching?
4. How might T&F searching impact practice?
5. What features are most useful?

Results of the Study
What scientists currently do Uses and Purposes of T&F indexing Suggestions for success
![Page 17: Indexing of Tables and Figures: Scientists’ Reaction Carol Tenopir University of Tennessee ctenopir@utk.edu web.utk.edu/~tenopir](https://reader031.vdocuments.us/reader031/viewer/2022013012/56649f295503460f94c4338f/html5/thumbnails/17.jpg)
What they currently do
Search for photographs and maps more than tables, figures or graphs
Use Google most often Level of satisfaction with searches
consistently rated low locating objects is “difficult” “in general, academic figures, tables, and
graphs are not available to search”
![Page 18: Indexing of Tables and Figures: Scientists’ Reaction Carol Tenopir University of Tennessee ctenopir@utk.edu web.utk.edu/~tenopir](https://reader031.vdocuments.us/reader031/viewer/2022013012/56649f295503460f94c4338f/html5/thumbnails/18.jpg)
Potential Uses and Purposes
1. To find relevant articles they would not otherwise find
2. To retrieve and use images
3. To compare their work with others’
4. To support analysis
![Page 19: Indexing of Tables and Figures: Scientists’ Reaction Carol Tenopir University of Tennessee ctenopir@utk.edu web.utk.edu/~tenopir](https://reader031.vdocuments.us/reader031/viewer/2022013012/56649f295503460f94c4338f/html5/thumbnails/19.jpg)
Potential Use: To find articles they would otherwise miss
“Sometimes tables, figures, maps, etc. are ‘hidden’ in other papers. This search tool gives me the opportunity to find these items too”
“…possibility to find information that might be unnoticed in a traditional database”
“…ability to find data that may not be reflected in the title and abstract of the article”
![Page 20: Indexing of Tables and Figures: Scientists’ Reaction Carol Tenopir University of Tennessee ctenopir@utk.edu web.utk.edu/~tenopir](https://reader031.vdocuments.us/reader031/viewer/2022013012/56649f295503460f94c4338f/html5/thumbnails/20.jpg)

Potential Use: To retrieve and use images
It would be useful “when looking for information difficult to retrieve in written form”
Specific instances noted: “looking for geologic maps of a specific area” “for a quick assessment of photographic quality
in cytogenetics research” “when I need a specific graph, map, photograph,
or figure that would be for presentations or teaching”

Potential Use: To compare their work with others’
It would be useful when “writing original manuscripts and comparing data from other researchers to your own findings”
Another researcher refers to “seeking published data with which to compare models”
“Knowing or suspecting that a specific experiment has been done, I can look for the data and compare to one I might do or may have already done”
![Page 25: Indexing of Tables and Figures: Scientists’ Reaction Carol Tenopir University of Tennessee ctenopir@utk.edu web.utk.edu/~tenopir](https://reader031.vdocuments.us/reader031/viewer/2022013012/56649f295503460f94c4338f/html5/thumbnails/25.jpg)
Potential Use: To support analysis
Participants anticipate using the objects retrieved : for review articles to “be inspired by how other researchers set
up figures/tables” to “expose me to different areas in which
similar methods are used”
![Page 26: Indexing of Tables and Figures: Scientists’ Reaction Carol Tenopir University of Tennessee ctenopir@utk.edu web.utk.edu/~tenopir](https://reader031.vdocuments.us/reader031/viewer/2022013012/56649f295503460f94c4338f/html5/thumbnails/26.jpg)
Potential to change practice
“I discovered some new publications in areas where I thought I knew all.”
“…made me think about different ways that data is conveyed…I’ll design my own future graphs and figures to better ‘stand alone’ as a result.”
“I actually did a few successful searches where unexpected and interesting information came up.”
![Page 27: Indexing of Tables and Figures: Scientists’ Reaction Carol Tenopir University of Tennessee ctenopir@utk.edu web.utk.edu/~tenopir](https://reader031.vdocuments.us/reader031/viewer/2022013012/56649f295503460f94c4338f/html5/thumbnails/27.jpg)
Suggestions for Success
Images must be of high quality with ability to enlarge thumbnail images
The context of the whole article is very important—in fact it may be dangerous to see images without the context
Allow table contents to be searchable and support extraction of data from tables

In conclusion
Scientists use journal issues and articles for many different reasons, including current awareness, research and writing, and teaching
They read many articles each year, from a variety of journals and the amount of reading is going up
Journal issues are good for browsing and current awareness; articles found by searching are important for research and teaching
![Page 32: Indexing of Tables and Figures: Scientists’ Reaction Carol Tenopir University of Tennessee ctenopir@utk.edu web.utk.edu/~tenopir](https://reader031.vdocuments.us/reader031/viewer/2022013012/56649f295503460f94c4338f/html5/thumbnails/32.jpg)
And…
Sometimes scientists need just a part of an article and they need systems that help them read more quickly
Providing access to tables and figures, within the context of the article as a whole, can help scientists in many ways.
Librarians and publishers must think at many levels of granularity—journal issues and whole articles AND parts of articles such as tables and figures.
