Hybrid material

Things in booksHybrid material is collection material in which two or more works in different formats (printed text, graphics, manuscripts, or realia) share a volume or other physical container (for example, a manuscript letter tipped into a printed book). Compare Sammelbands for different works of the same format bound together after publication/creation.

Intellectually self-contained works

Intellectually self-contained works generally should have a separate record.

  • Add copy note stating creator, title, year, location within, and shelfmark of the other work
    • In cases of interleaving, add genre term for Interleaved copies (Provenance) to both records
  • Make an associated work added entry (700 ǂa ǂt / 730; second indicator blank) for the work in the other aspect if the works are fully physically integrated (e.g., interleaved). Append ǂ5 DFo to the work added entry on records for published material. Reciprocal 700/730s are not necessary for normal bound-with situations (i.e. Sammelbands).
  • Make a host item added entry (773) for the work in the other format if the relationship is unequal (e.g., single item being cataloged is tipped into a volume containing a larger work). Include ǂ5 DFo if the work you are cataloging is published. See discussion

In M.b.4 (ms. content) bib record:

245 00 Sonnets and other poems ǂh [manuscript], ǂf ca. 1790-1800.
520 2_ Manuscript sonnets and poems interleaved with Charlotte Smith's Elegiac sonnets, 1786. 
700 1_ Smith, Charlotte Turner, ǂd 1749-1806. ǂt Elegiac sonnets. 

In M.b.4 (printed content) holdings record:

100 1_ ǂa Smith, Charlotte Turner, ǂd 1749-1806.
245 10 ǂa Elegiac sonnets / ǂc by Charlotte Smith.
730 0_ Sonnets and other poems. ǂ5 DFo 
852 ǂz Interleaved with manuscript sonnets and poems, cataloged separately as M.b.4 (ms. content), under title Sonnets and other poems [manuscript], ca. 1790-1800.

Subordinate material

A work that is not intellectually self-contained generally should not have a separate record (e.g., annotations in printed books, drawings in manuscripts). In the past, separate cards were made for ms. annotations in printed books. In contrast, book catalogers will now add a description of the manuscript material to the book record, and ms. catalogers will skip*** those cards (for recon) and books (for original cataloging).

  • When working with cards: Make a photocopy of the card(s), front and back, keeping records separate since they may be distributed to different catalogers. See discussion
  • When doing original cataloging: Fill out a call slip for the host item. Suggest note for holdings record of printed work.
  • Formulate copy-specific added entries and/or genre terms (e.g. Annotations, Fists, etc) to be included in the bibliographic record, since manuscript content is not getting a separate record.
  • In certain circumstances, a curator may decide that subordinate material merits its own record. Generally, this would be the case if the interleaved materials have little or no direct intellectual connection to the bound item or if the creator/main entry for these materials would need to differ from that of the bound item. If instructed to make a separate record for the subordinate material, follow the procedure above for intellectually self-contained works of different aspects sharing a physical container.

Material removed from a volume or other physical container

See Things in books For a manuscript:

561  Removed from: Sir Edward Coke, A booke of entries, 1614, p. 584 (STC 5488).
700 1_ Coke, Edward, ǂc Sir, ǂd 1552-1634. ǂt Booke of entries. ǂ5 DFo

Give edited information for holdings note in original host item record. Do not make added entries for removed items.

852 ǂz 1 letter, found inserted on p. 584, removed to manuscript collection (X.c.130).


Instructions below assume hybrid volumes of two formats; amend as necessary for hybrid works containing three or four.

  • Email appropriate cataloger of other aspect(s) (cc'ing head of cataloging)
    • Indicate if original cataloging is needed or if only a copy-specific note (and any copy-specific tracings &/or genre terms, if appropriate) need to be added to an already existing record
    • Include suggested wording for copy-specific notes, so that it can be easily copied and pasted into record.
  • Give to cataloger (or place on their shelves, if have item in hand)
    • Printed copy of above email
    • Copies of all pertinent bibliographic records (or copy of catalog cards, if recon), indicating their relationship to each other
    • Call slip made out to the cataloger OR item with call slip corrected to indicate correct cataloger.
