PROJECT BACKGROUND Reading Chicago Reading (RCR) explores large scale reading behavior through the analysis of the One Book One Chicago (OBOC) program s book finalists and: 1) Chicago Public Library circulation data 2) Demographic data about diverse Chicago communities Next step: 3) Adding text features extracted from the OBOC book finalists
INFORMATION NEED RCR asked DePaul library staff to consider the following information need(s) and recommend potential solutions: For given work(s), about which author and title are known, are there any OBOC English language manifestations available in the HTRC Extracted Features dataset? Do any open programmatic tools exist that can help digital humanities scholars and librarians find and obtain this content in an mostly seamless and automated way? If not, do separate open programmatic tools exist that RCR could link together to achieve this end?
A SERIES OF APIS Technical Services staff considered these information needs and proposed using a combination of OCLC and HathiTrust APIs to progress from known author and title metadata to the desired output.

HTRC EXTRACTED FEATURES DATASET IN JSON Although we have established that a certain volume of a work is available in the HathiTrust extracted features dataset, is this the volume we are interested in?

TAKEAWAYS Complexity stems from the following factors: any number of possible manifestations/items of a work may or may not be available on a system many APIs assume knowledge of item level IDs as a starting point for obtaining data This type of automated known-work search to find/explore any available item" for computational purposes is not very common yet. We expect more requests as digital humanities and other researchers seek entire machine readable texts and text metadata for computational analysis. Technical services librarians can use their knowledge of metadata to assist digital humanities scholars and other researchers in determining useful API searches/calls utilizing known metadata and for retrieving additional textual metadata that might be of use. RCR project developers hope to make alpha prototype program(s) available on GitHub soon.
