This page provides a historical technical overview.
The Florida Historical Quarterly was originally included in the Florida Heritage Collection. Due to its high volume of use and need for direct access, it was made a separate collection upon the Digital Projects Planning Committee's suggestion in 2005.
OVERVIEW AND WORKFLOW
Digitization of the Florida Historical Quarterly and contribution of the catalog record for the digitized version to a central database are the responsibility of the University of Central Florida Libraries. The Libraries perform or outsource the digitization and create files of structural metadata describing the relation of images to logical parts of the resource. The structural metadata record and the set of images for each resource were transmitted to FCLA, where the data was loaded into DLXS application on a central UNIX server. Identifiers which serve the function of persistent URLs pointing to the DLXS application were inserted into the catalog record.
IMAGE CAPTURE AND CONVERSION
Scanning of volumes 1 through 77 was outsourced to the Digital Image Processing Lab (DIPL) at the University of Central Florida. The binding was removed from the volumes and the individual pages were fed through a Kodak high speed duplex scanner. Image capture adhered to the standards promulgated by the Cornell Department of Preservation and Conservation (see Digital Imaging for Library and Archives, Kenny and Chapman, 1996). A Quality Index of 5 or better for visual images is required. The Digital Services unit of the University of Central Florida Libraries is responsible for scanning additional volumes of the Florida Historical Quarterly beginning with volume 78. A Kodak i-200 series flatbed scanner is being used for this purpose. OCR is not currently being performed. Master TIFF images and JPEG derivatives were submitted to FCLA, which creates a derivative PDF for each issue. Creation of PDF files is a function performed by the locally written PALMM materials loader software. The loader calls LeadTools custom ActiveX control to open sets of JPEG images, and then uses Thomas Mertz's PDFLib software to build the PDF.
RESOURCE DESCRIPTION -- CATALOGING
A full MARC catalog record for the Florida Historical Quarterly is available and maintained in a union database of all Florida Heritage materials at FLVC and is also contributed to the OCLC WorldCat. When new volumes and issues are loaded, the persistent URLs in the catalog record will be updated to reflect all the available materials. A small portion of analytic records were created by the loader and accessible through the union catalog as well.
RESOURCE DESCRIPTION -- STRUCTURAL METADATA
A file of structural metadata is created for every document to indicate the relationship between the physical units of digitization (TIFF, JPEG and other images) and the logical units of publication (pages, chapters, and other parts). The metadata formats used was FCLA's Metadata eXchange Format (MXF).
IMAGE LOADING, STORAGE and NAVIGATION
For each issue that is digitized, a directory containing one XML file and a set of images was sent by FTP from the University of Central Florida Libraries to FCLA. The metadata and images are processed by a locally written loader, which first checks that all the image files referenced by the XML are present, copies the images into a data storage server, and converts the structural metadata into DLXS maintained on a UNIX server. If instructed, the loader will also create derivative formats such as PDF files. Access and navigation was provided by DLXS middleware. For materials that come with ASCII text obtained by performing Optical Character Recognition (OCR) on textual image files, this "dirty ASCII" will be used for full text retrieval of the documents as well. Persistent URLs referencing the server application were created by program and inserted into the bibliographic record describing the resource.
The cataloging record is loaded into a shared central library management system, a locally developed application based on NOTIS, on an IBM mainframe. The records can be searched through the SUS Libraries' online catalog application, WebLUIS. Once the record is retrieved, the URLs in the bibliographic record were used as hotlinks to the DLXS application, which initially presents a Table of Contents display.
