LH Bailey used the collection in support of his publications, such as:
• Hortus Third
• Manual of Cultivated Plants
• Annals of Horticulture

10. How was it used?
1889 Introduction of

11. Why Digitize Seed & Nursery Catalogs?
• Taxonomists
• Discover dates of early introductions of
new plants
• Gardeners
• Historical availability and uses of
traditional cultivars of heirloom annuals
and perennials
• Museums and botanical gardens
• Recreate historical gardens
• Plant breeders
• Look for descriptions of plants with unique
disease and pest resistance
• Historians of art and illustration
• Drawn to the striking representations of
flowers, fruit & vegetables
• Historians of printing
• Catalogs document changes in printing

Purposeful Gaming and BHL:
engaging the public in improving & enhancing
discovery & access to digital texts

30. BHL Problem Statement:
• Major challenge for digital libraries:
• full-text searching of scanned texts is
significantly hampered by poor output from
Optical Character Recognition (OCR) software.
• Historic literature has proven to be particularly
problematic because of its tendency to have
• varying fonts
• varying typesetting
• varying layouts
• ink bleed-through
• foxing
• other physical condition issues

32. • Building an online game to crowdsource the correction of
inaccurate OCR
• Crowdsourcing the transcription of inaccurate OCR and
handwritten texts
• Adding new content types upon which to test the approach
• Seed & Nursery Catalogs & Seed Exchange Lists
• Test OCR correction on this content type
• Crowd-source the transcription when needed
• Field Notebooks,
• Handwritten, OCR virtually impossible
• Crowd-source the transcription
How are we engaging the public in
improving and enhancing the discovery and access to
digital texts in BHL?

33. Beanstalk

34. What happens with the game output?
• Multiple players enter the same character string for a
word, system considers it correct
• String of characters or the correct word is added to the
index
• Made available for searching & improves discoverability
• Games released, June 9, 2015
