Sponsorship

The images and descriptions of Walters manuscripts on this website were created with funding awarded to the Walters Art Museum by the National Endowment for the Humanities in two projects—Islamic Manuscripts of the Walters Art Museum: A Digital Resource (2008 to 2011) and Parchment to Pixel: Creating a Digital Resource of Medieval Manuscripts (2010 to present). Additional funding has been provided by an anonymous donor.

Intended audiences

The data on the Digital Walters is intended for aggregators, digital humanists, and scholars who have been directed here to procure high-resolution images of manuscript pages. It is presented in a manner most likely to ensure its long-term digital preservation. For those who would prefer to experience the data in more user-friendly ways, we suggest the following sites:

Manuscripts

Nearly all of the Walters’ collection of 128 Islamic codices and 60 loose leaves are available on the Digital Walters. All of them are accompanied by detailed manuscript description information in machine-readable TEI format. Because of their fragile condition or their inordinately large or small sizes, however, a few of our Islamic manuscripts could not be imaged as part of the Islamic Digital Resource project. The Walters is now digitizing its English, Dutch, German, Armenian, Byzantine and Ethiopian manuscripts for the Parchment to Pixel project. As with the Islamic manuscripts, conservation and size considerations may prohibit the digitization of some of these manuscripts.

Manuscript images and descriptions appear on this site as they are completed. Images are added frequently, as the digitization takes place. TEI manuscript descriptions also appear as they become available, but this may be as long as two years after the images are added, as their delivery depends on the completing to cataloging and an editorial review process.

The Manuscript images

Every element of each manuscript is digitized, including text folios, blank folios, flyleaves, later additions, stubs (whenever possible), and bindings (inner and outer boards as well as spine, fore-edge, head, and tail). Some elements of a manuscript may be imaged more than once. This is the case for Islamic bindings with envelope flaps, for example. For these, the first flyleaf on the flap side will be imaged with the flap, and without the flap.

Master images are captured at a resolution of at least 600 pixels per inch of the image subject. Illuminated folios and other decorated elements of a manuscript are captured at higher resolutions, ideally 1200 pixels per inch where the dimensions of the object allows. The dimensions of some larger manuscripts make capturing at 1200 PPI impossible. For these, the highest resolution possible is used instead.

Once all of the images for a manuscript have been captured they are color-corrected, deskewed, and cropped. Four types of images are delivered for each manuscript element:

  1. a full-sized, archival TIFF image, which includes a ruler and a Macbeth color-calibration chart in the frame (600 PPI text folios/ 1200 PPI illuminated folios);
  2. a 300 PPI TIFF suitable for print publication;
  3. a standard all-purpose (SAP) JPEG intended for web use, that is 1800 pixels on its longest side; and
  4. a thumbnail JPEG that is 190 pixels on its longest side.

The ruler and Macbeth color-calibration chart are cropped out of the frame for the three non-master images.

File names indicate the file type or resolution through a “tag,” which is the last segment of the file name before the extension ‘.tif’ or ‘.jpg.’ The following file names are for the 300 PPI TIFF and standard all-purpose and thumbnail JPEG images for W.583, image serial no. 1:

  • W583_000001_300.tif
  • W583_000001_sap.jpg
  • W583_000001_thumb.jpg

For archival master images, the resolution is encoded in the file name. The following file names for master TIFF images show how this works:

  • W583_000008_600.tif
  • W666_000016_1200.tif
  • W658_000056_886.tif
  • W589_000008_1050.tif

For these for images, the names indicate resolutions of 600, 1200, 886, and 1050 PPI, respectively. The first image, image serial no. 8 from manuscript W.583, has a resolution of 600 PPI. The second image has the standard maximum resolution of 1200 PPI. The third and fourth images come from manuscripts whose large dimensions limited their maximum resolutions to 886 and 1050 PPI each.

Manuscript descriptions

Two types of descriptive metadata are provided for manuscripts and manuscript images: Dublin Core for basic metadata and TEI P5 manuscript descriptions for cataloging information.

Dublin Core

Basic metadata is provided for manuscripts and individual archival TIFF images using Dublin Core Metadata Initiative elements. This basic metadata is presented on the manuscript’s HTML page and is also stored in the ImageDescrption tag of the TIFF header of each individual archival image. The following elements are used.

  • Identifier: the shelf mark for manuscripts (e.g., W.582), and the image serial number for images (e.g., W582_000001)
  • Creator: always the Walters Art Museum
  • Contributor: one entry for each project participant responsible for the creation of the manuscript’s data set
  • Date: the date of web page or image creation
  • Title: the title of the manuscript (e.g, “Walters Ms. W.579, Prayer”)
  • Description: a description of the manuscript or image
  • Source: source of the object used to create the image or image collection
  • Type: Image for individual images; Collection for all images of a manuscript
  • Format: image/tiff for images, text/html for a manuscript web page
  • Subject: keywords describing the manuscript or imaged folio
  • Rights: license and usage terms

TEI manuscript descriptions

Manuscript cataloging incorporates not only the identification of the author and title of works, and the date of origin and provenance of the manuscripts, but also detailed descriptions intended to aid the palaeographer, codicologist, art historian, historian, and philologist. A description of the manuscript cataloging, with technical and non-technical detail, is given in the document ManuscriptDescription.html.

How to use this data set

This data set contains complete digital surrogates for the manuscripts it contains. Walters manuscripts are provided with machine-readable TEI manuscript descriptions. The main purpose of the Digital Walters is to give access to entire manuscripts via web-based tools like FTP and RSYNC, which employ the site’s directory structure. We also provide HTML access to the files, which is easier for the individual user to navigate. HTML and directory structure access are described below.

HTML access

To ease human navigation of the site, a series of web pages is provided. The entry point is the ACCESS_WALTERS_MANUSCRIPTS.html file, which lists all of the Walters manuscripts currently on the site. The amount of detail for each manuscript varies, based on the progress of the manuscript’s cataloging.

A typical entry for a manuscript will look something like this:

W.586, Work on the duties of Muslims toward the Prophet Muhammad with an account of his life, ʿIyāḍ al-Yaḥṣubī (d. 544 AH / 1149 CE), Arabic (1777 CE, Turkey)

Browse manuscript | Manuscript Description (TEI format)

This entry lists the shelf mark, the title assigned to the manuscript, the author if known, the language, and the manuscript’s provenance. Beneath the summary are a link to the manuscript’s page, and a link to the manuscript’s description in TEI format if it is available.

Each manuscript listed in this table of contents has its own page. The individual manuscript page has a list of all of the images associated with the manuscript and the manuscript’s Dublin Core metadata (including identifier, date, title, description, creator, contributors, source, type, format, subjects, and rights).

A simple entry is provided for each manuscript image. An entry looks like the following.


  1. Upper board outside

    W.586, Upper board outside

The entry features a thumbnail version of the image (in this case the front cover of the manuscript), links to each of the images, and the size of each file.

Directory access

The primary intent of the Digital Walters is to provide access to the images and manuscript description data of the Walters’ NEH-funded manuscript digitization projects. There are a number of ways to access this data through Internet-based tools described in the Technical ReadMe file (http://thedigitalwalters.org/04_TechnicalReadMe.html). As a result, the primary method for accessing manuscript images is through the site’s directory structure.

The directory structure, starting from the website root is as follows:

01_ACCESS_WALTERS_MANUSCRIPTS.html  # list of Walters manuscripts
02_ACCESS_OTHER_BOOKS.html          # list of other books here
03_ReadMe.html                      # this file
04_TechnicalReadMe.html             # technical information

       |--- W13/
       |--- ...

Within each manuscript directory, manuscripts are collected in a data delivery package called a Bag, which is defined by the BagIt specification and described in detail in the Technical ReadMe document. A typical manuscript directory has this structure:

W579/
 |--- bag-info.txt                  # description of the data package
 |--- bagit.txt                     # bagit protocol version, text encoding

                   |--- W579_000003_thumb.jpg
                   |--- ...

Apart from the file extension, opening shelf mark segment (W579) and final identifying segment (for example, 300, 1200, sap, and thumb), each file has a serial number expressed in a six-digit text value ending in a sequential number: 000001, 000002, and 000003. The identity of the file contents, whether it’s a binding element, flyleaf, or folio is stored in the metadata.xml file and in the manuscript description.

Identifying file contents for human users is aided by a system of static HTML files accessible from the [01_ACCESS_WALTERS_MANUSCRIPTS.html][] file, which is discussed above.

Other collections on the Digital Walters

In addition to Walters manuscripts, this data set also includes images from books and manuscripts from non-Walters collections. Among them are a Galen palimpsest and a small number of books and manuscripts in the OtherCollections directory.
