Psychological Study of Art
grew in support of the Institute
for the Psychological Study of the Arts (IPSA) at the University of Florida.
Today the collection is open for contribution from any
PALMM member or partner organization and collection "ownership" extends
beyond the University of Florida. Text digitization entails
either or both page-image scanning and text conversion.
Page-image scanning usually is completed in-house by
the contributing organization, though the institutions
vendors scanned some contributions. Text conversion and
mark-up is most commonly vended by contributing institutions.
However, some of the titles in this collection were "born
digital", usually in HTML or word-processing formats,
converted in-house to TEI for deployment as part of this
collection. Some contributing institutions rely upon
Optical Character Recognition (OCR) for in-house text
conversion.

COPYRIGHT
Participating libraries are responsible for clearing
copyright. Copyright for the majority of texts in this
Collection is held by authors who extended their permission
for digitization and internet distribution through Psychological
Study of the Arts. Authors reserve all rights. For copyright

Copyright information page.
CATALOGING
Participating libraries are responsible for creating
full MARC catalog records for the materials selected
from their own collections. Catalog records form the
core bibliography of this collection. Cataloging records
are maintained in a union database of all Psychological
Study of the Arts materials at the Florida Center for
Library Automation (FCLA) and records for digitized resources
are also contributed to the OCLC WorldCat.
Cataloging is expected to adhere to guidelines developed
by the Technical Services Planning Committee Cataloging
and Access Guidelines for Electronic Resources (CAGER).
Complete MARC cataloging instructions can be found in
these Guidelines.
IMAGE CAPTURE
Each library performs or vends its own scanning; quality
control is always complete independently in-house. Image
capture must adhere 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.
Digital masters, archived as uncompressed TIFF images,
are created as the direct result of scanning source materials,
using a variety of scanning hardware, primarily flat-bed
scanners. Bit-depth is appropriate to the source and
its anticipated use, and may be bitonal, 8-bit grey,
24-bit color, or greater. Color images are created and
maintained in the sRGB color-space. Both grey and color
images are calibrated and scanned to within the tolerances
promulgated by the Library of Congress for the American
Memory project. Images created from microfilmed sources
reflect the quality of the source microfilm.
TIFF images are used to create JPEG derivatives using
Adobe Photoshop in a batch process. The TIFF image is
resized setting the width to 630 pixels and the height
accordingly. Creation of PDF files is a function performed
by locally written 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.
TEXT CONVERSION & MARK-UP
Each library performs or vends its own text conversion
and mark-up; quality control is always complete independently
in-house. The majority of text versions are produced
by vendors using re-keying (i.e., double-keying) method,
working from the page-image TIFFs. Some vendors and most
in-house conversion employ optical character recognition
(OCR) of TIFF images. Regardless the conversion method,
a minimal accuracy rate of 99.995% is required. Mark-up employs a localized subset of Text Encoding Initiative
(TEI) tags optimized for PALMM
Textual Collections. Where
page images exist, text is linked to views of the page
from which has been converted.
Texts born digital are repurposed for deployment in
Psychological Study of the Arts. HTML or word processor
file format mark-up is converted to TEI.
STRUCTURAL METADATA
For titles contributed in text, TEI is used to define
document structure and a table of contents. For titles
in page-image only versions, structural metadata is created
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 format used is METS-based.
DEPLOYMENT
Digitized volumes (image files, text & mark-up,
and metadata) are sent via FTP from the contributing
institution to FCLA, which subsequently loads them onto
the Textual Collections server. This server runs XPAT
5.0 software, distributed by the University of Michigan's
Digital Library eXtension
Service (DLXS). Once loaded,
persistent URLs (PURLS) are created by program and inserted
into the bibliographic record describing the resource. |
