| 01 | Manifestation of | Product A is or includes a manifestation of work X. (There is a direct parent–child relation between work X and the product). The instance of <RelatedWork> must include an identifier for work X | 9 | 59 |
| 02 | Derived from | Product A is or includes a manifestation of a work X which is derived (directly) from related work W in one or more of the ways specified in the former ISTC rules. (There is a relationship between a grandparent work W and a parent work X, and between that parent work and the product.) This relation type is intended to enable products with a common ‘grandparent’ work to be linked without specifying the precise nature of their derivation, and without necessarily assigning an identifier to the product’s parent work X. The instance of <RelatedWork> must include an identifier for work W. Codes 20–30 may be used instead to provide details of the derivation of work X from work W | 9 | 59 |
| 03 | Related work is derived from this | Product A is a manifestation of a work X from which related work Y is (directly) derived in one or more of the ways specified in the former ISTC rules. (There is a relationship between a parent work X and a child work Y, and between the parent work X and the product.) The instance of <RelatedWork> must include an identifier for work Y. Codes 40–50 may be used instead to provide details of the derivation of work Y from work X | 13 | 59 |
| 04 | Other work in same (bibliographic) collection | Product A is a manifestation of a work X in the same (bibliographic) collection as related work Z. (There is a relationship between the parent work X and a ‘same collection’ work Z, and between the parent work X and the product.) The instance of <RelatedWork> must include an identifier for work Z | 13 | 59 |
| 05 | Other work by same contributor | Product A is a manifestation of a work X by the same contributor(s) as related work Z. (There is a relationship between the parent work X and a work Z where X and Z have at least one contributor in common, and between the parent work X and the product.) The instance of <RelatedWork> must include an identifier for work Z | 13 | 59 |
| 06 | Manifestation of original work | Product A is or includes a manifestation of work X. (There is a direct parent–child relation between work X and the product, and work X is original, ie not a derived work of any kind – there is no work W.) The instance of <RelatedWork> must include an identifier for work X. See code 01 if the originality of X is unspecified or unknown | 59 | |
| 21 | Derived from by abridgement | Product A is or includes a manifestation of a work X which is derived directly from related work W by abridgement. (There is a relationship between the grandparent [unabridged] work W and the parent [abridged] work X, and between the parent work X and the product.) The instance of <RelatedWork> must include an identifier for [unabridged] work W. <EditionType> of product A would normally be ABR. See code 02 if the method of derivation of X from W is unknown or unstated. The [abridged] parent work X may be identified using a separate instance of <RelatedWork> with relation code 01 | 59 | |
| 22 | Derived from by annotation | Product A is or includes a manifestation of a work X which is derived directly from related work W by annotation. The instance of <RelatedWork> must include an identifier for [unannotated] work W. <EditionType> of product X would normally be ANN, VAR etc. See code 02 if the method of derivation of X from W is unknown or unstated. The [annotated] parent work X may be identified using a separate instance of <RelatedWork> with relation code 01 | 59 | |
| 23 | Derived from by compilation | The content of the work X has been formed by compilation of work W and another work Z. The instance of <RelatedWork> must include an identifier for work W. <EditionType> of product A may be CMB. Work Z may be identified using a separate instance of <RelatedWork> with code 23. The compiled parent work X may be identified using a separate instance of <Related> work with relation code 01 | 59 | |
| 24 | Derived from by criticism | The content of the work W has been augmented by the addition of critical commendary to form work X. The instance of <RelatedWork> must include an identifier for work W. <EditionType> of Product A would normally be CRI | 59 | |
| 25 | Derived from by excerption | The content of the work X is an excerpt from work W. The instance of <RelatedWork> must include an identifier for [complete] work W | 59 | |
| 26 | Derived from by expurgation | Offensive or unsuitable text material has been removed from work W to form work X. The instance of <RelatedWork> must include an identifier for [unsuitable] work W. <EditionType> of Product A would normally be EXP | 59 | |
| 27 | Derived from by addition (of non-text material) | The content of work W has been augmented by the addition of significant non-textual elements to form work X. The instance of <RelatedWork> must include an identifier for [unaugmented] work W. <EditionType> of product A may be ILL, ENH etc | 59 | |
| 28 | Derived from by revision | The content of work W has been revised and/or expanded or enlarged to form work X [including addition, deletion or replacement of text material]. The instance of <RelatedWork> must include an identifier for [unrevised] work W. <EditionType> of product A may be REV, NED, etc, or A may be numbered | 59 | |
| 29 | Derived from via translation | The content of work W has been translated into another language to form work X. The instance of <RelatedWork> must include an identifier for [untranslated] work W | 59 | |
| 30 | Derived from via adaptation | The content of work W has been adapted [into a different literary form] to form work X. The instance of <RelatedWork> must include an identifier for [unadapted] work W. <EditionType> of product A would normally be ADP, ACT etc | 59 | |
| 31 | Derived from by subtraction (of non-text material) | The content of work W has been modified by the removal of significant non-textual elements to form work X. The instance of <RelatedWork> must include an identifier for work W | 59 | |
| 41 | Related work is derived from this by abridgement | Product A is a manifestation of a work X from which the related work Y is (directly) derived by abridgement. (There is a relationship between the parent [unabridged] work X and the child [abridged] work Y, and between parent work X and the product.) The instance of <RelatedWork> must include the identifier for [abridged] work Y. See code 03 if the method of derivation of Y from X is unknown or unstated. The [unabridged] parent work X may be identified using a separate instance of <RelatedWork> with relation code 01 or 06 | 59 | |
