Digital resource analysis

Note

"Print" is used here as shorthand for physical resources; audio recordings, etc. are therefore included as 'print' material.

Overview

(click to expand)

The aim of this exercise is to identify which records describe material which is linked to (as opposed to stored on site).

Criteria

A record which describes linked to material should have:

  • 856 field - containing the external link
    • 1st indicator: # or 4
    • 2nd indicator: #, 0 or 8
    • Subfields $u (the URL) and $y (display text for the online catalogue)
  • 859 field - digital resource flag
    • Subfield $a should contain ELD, ORR or XLD
    • Subfield $b should also be present, and should contain a code similar to that found in field DRT subfield $a
  • DRT field - digital record type
    • Subfield $a should contain one of:
      • DCW
      • ETHOS
      • GOOGLEBOOKS
      • LD-ebooks
      • LD-escores
    • Other values are permitted in DRT $a, but do not appear in records for linked-to resources.

Exceptions

  1. In practice, the indicators of field 856 cannot be relied upon.
  2. Records for ETHOS material do not routinely contain 856 $y.
  3. There are some classes of material where the DRT and 859 fields are not present. These include:
    • Records containing links to the British Newspaper Archive

856 in holdings records

(click to expand)

There are 581 instances of field 856 in 574 records in BLL60. Records can be downloaded from Reports/Records for linked-to material/Links in holdings records.

The records fall into 7 categories:

SFX records

SFX e-resources enable the BL to provide access to content that the Library does not ingest.

Analysis

(click to expand)

Records in BLL01 were categorised according to:

  • Field 852
    • Presence or absence of shelfmark
    • Whether the shelfmark(s) present appears to relate to a physical or digital resource
  • 856 fields
    • Presence of subfields $u and $y
    • Presence and content of subfield $x
  • 859 fields
    • Content of subfields $a and $b
    • Content of subfield $c (which indicates SFX records)
  • DRT fields
    • Content of subfield $a
  • EST fields
    • Content of subfield $a
  • STA field
    • Content of subfield $a

Shelfmarks containing "Digital Store" or "ELD.DS" were recorded as relating to digital resources. Shelfmarks containing "e-media" were recorded as relating to physical resources (CD-ROMs) except where it could be explicity established otherwise. All other shelfmarks were assumed to indicate physical resources.

The table below lists the categories found, and the number of records in each.

It is logically possible for a print-like shelfmark and an external link to appear in the same record - for example in the case of an electronic publication distributed on CD-ROM and online.

The full analysis is available to download as a spreadsheet or in more detail .

Lists of record IDs for each category can be found in [this folder] (NOT YET AVAILABLE).

Finally, the categories above were aggregated into broader categories, as in the table below.

In this context No shelfmark indicates an 852 field without a shelfmark (this usually means that the field is lacking subfield $j).
