MARC field 856 in the Bibliographic and Holdings format contains information needed to locate and access an electronic resource. The field may be used in a record for a resource when that resource or a subset of it is an electronic resource (e.g., in the record for an online journal); when an electronic version of the resouce described in the record is available (e.g., to link to digital images of a vault book in the record for that book); and when an electronic resource related to the resource described in the record is available (e.g., to link to a blog post or article about the manuscript described in the record).

Staff add identical 856 fields to the Bib record and the Holdings record, but only the one in the Holdings record displays in Hamnet.

Commonly-used tags

Indicators

First indicator

4 - HTTP

Second indicator

0 - Resource (Use when the item being described is electronic in nature, such as an online journal) 
1 - Version of resource (Use for electronic images of the resource being described)
2 - Related resource (Use for resources related to the resource being described, such as online tables of contents or a finding aid to a manuscript collection) (for additional information, see 555_Cumulative_Index_Finding_Aid)

Subfields

‡u - Uniform Resource Identifier (R)
‡x - Nonpublic note (R)
‡y - Link text (R) [not used at the Folger, use ‡z instead]
‡z - Public note (R)
‡3 - Materials specified (NR) 

Policy and formulation

When the bib record is for original material in the Folger collection

  • Make hypertext links to Folger digital images or related resources to the material being described.
  • Do not add links to non-Folger reproductions, even if they reproduce the Folger copy (previously, we sometimes made additional holdings for EEBO links and Hathi Trust links; now, those would be separate bib records).
  • When linking to a complete digital reproduction of a codex from the Folger, use the phrasing "Cover-to-cover images of Folger Shakespeare Library [call no. and copy no.]"; or the citation form for manuscripts, "Cover-to-cover images of Folger Shakespeare Library MS [call no.]". When the fully-reproduced item-in-question is not a codex, use instead the phrasing "Digital image(s) of Folger Shakespeare Library [call no. and copy no.]"; or the citation form for manuscripts, "Digital image(s) images of Folger Shakespeare Library MS [call no.]".
    • Folger practice: use ‡z for link text.
  • When linking from a bibliographic record in Hamnet to only one or more (but not all) images from an item, use the following steps:
    • Link to the thumbnail page rather than the image details page. If additional images are created for that title, the link will be revised at that point.
    • Use this text for the 530 ‡a: Portions also available as a digital reproduction. Or, if there's also a holdings record for microfilm, note both in a single note Also available on microfilm and portions available as a digital reproduction.
    • Use this text for the 856 ‡z: Selected image(s) from Folger Shakespeare Library [insert call no. here; if a mss, precede the call no with 'MS']
  • If both collection-level and item-level records exist in Hamnet, provide digital image links in the item-level records only.

When the bib record is for an electronic resource

N.B. when linking to a non-Folger reproduction (e.g., ECCO or Google Books), even if the reproduction is of a Folger item, give the electronic resource its own bib record (that is, do not treat it as an additional holding on a record for the physical resource).

  • Use 2nd indicator "0"
  • Use resource's URL in $u (see below for exception)
  • Do not provide additional link text
  • Use the appropriate 852$h (see Call numbers: Electronic resources


 8528_ $$aUS-DFo$$bEleRes$$hFreely available
 85640 $$uhttps://hdl.handle.net/2027/heb.99045


Exception: If the URL is a referrer URL that cannot be made public use the request system URL in $u and provide explanatory text in $x (non-public note) and $z (public note)

When adding LUNA links to the bib record for the original material

These instructions partly repeat what's above, but are given here separately for the benefit of non-catalogers adding LUNA links to bib records.

  • Make hyperlinks to all Folger reproductions (including incomplete reproductions) in Luna. In the case of boundwiths, links can additionally be made to the entire volume.
  • In the Voyager cataloging module:
    • Find the bib record and add a 530 field (or edit an existing one) that says "Portions also available as a digital reproduction."; or "Also available as a digital reproduction." When possible, combine such notes with "Also available on microfilm" notes.
    • Open the MARC holdings record for the correct copy of the material and add an 856 field containing the URL and the sppropriate link text. Copy this 856 field into the bib record.

When adding Folgerpedia links

In the Voyager cataloging module, in both the Bib and Holdings record, add an 856 field containing the URL and the link text: "Folgerpedia article about Folger Shakespeare Library [call no.]"

  • If the Folgerpedia article contains a full transcription, add "(with transcription)" after the call number in $z of the 856 field; if the Folgerpedia article contains a partial transcription, use "(with partial transcription)" instead.

  • PDF transcriptions may be added to Folgerpedia, and a link to the PDF should be added to both the Bib and Holdings record in the 856, with the link text: "Transcription of Folger Shakespeare Library [call number] (pdf)" or "Partial transcription of Folger Shakespeare Library [call number] (pdf)".

Creating LUNA links for the 856

Locate the image or set of images by searching in "Hamnet Holdings ID":

  • In Luna, choose "Advanced Search" and use the third row of search boxes (i.e. the one that provides "find this exact wording:"). Then choose "Hamnet Holdings ID" from the second field dropdown. Type in the holdings ID of the copy that is being linked to.
  • The results of the search should represent all the images currently in Luna for that specific copy.
  • From your search results, choose the "Sort Options" button (box with two up-and-down arrows). In the "Primary sort field", choose "Multiple Page Sort Order" from the dropdown. This indicates that the images will display in what was deemed the correct order when they were originally digitized (ex. front and back of a writ).
    • Note that in some cases you may need to have your primary sort set to "Call Number (PDI)" and set your secondary sort to "Multiple Page Sort Order" in order to get the best results.
    • Change the display options to show 250 items per page, and to show medium thumbnails.
    • Click "Share This" while on the results (thumbnail images) screen to get the permalink.
  • If there is and only ever will be one image for the item in question (e.g., a painting), open the image details view and get permalink from this screen. Be sure to right click on the thumbnail and open up the image detail view in a new tab; otherwise, the other search results, which may not be relevant, will show up as thumbnails to scroll through in the top-right corner of the single image view.
