Subject: [SACOLIST] SACO Shorts: Related terms (RTs) are reciprocal (common problem)


Earlier this month, we looked at the basics of related terms (RTs) and when to include them in proposals (see When to include related terms (RTs) in proposals, published on May 5). There is another important thing to keep in mind when proposing RTs: RTs are reciprocal. This means that headings related through RTs must have RTs to each other.



Examples



100 3   $a Jacobs family
500 3    $a Jacobus family
500 3    $a Jacoby family



100 3   $a Jacobus family
500 3   $a Jacobs family



100 3   $a Jacoby family
500 3   $a Jacobs family



150    $a Care of the sick
550    $a Home nursing



150    $a Home nursing
550    $a Care of the sick



150    $a Dwellings
550    $a Housing



150    $a Housing
550    $a Dwellings



Any time you propose a new or changed RT, you also need to propose an RT at the reciprocal heading as well. For example, the heading Natural gas distribution was established in November 2023 with the RT Natural gas pipelines. The proposer also had to submit a change proposal to Natural gas pipelines to add the RT Natural gas distribution.



Proposers frequently forget this step! If you forget to propose the reciprocal relationship-and if your RT is valid and follows the instructions in H 370<https://urldefense.com/v3/__https://www.loc.gov/aba/publications/FreeSHM/H0370.pdf__;!!KGKeukY!ycz_pfP7nwBDf4aiUVSzEeCpuuH_t3HV2uyd1I_UIyB2YCaPE86aTnNIttJQD01Bc_V2DxkA33MHO1w74g$ >-PTCP will try to make the proposal for you at point of review. Depending on the topic, we may need to reach out for additional information. As always, it helps PTCP work more efficiently when the necessary proposals are already in place.


SACO Shorts are quick tips that cover common proposal problems or frequently asked questions. SACO Shorts are published on the first and third Mondays of the month.
