Proposal No. 2025-01: Adding Subfields $i and $4 to Fields 368, 376, and 381 in the MARC 21 Authority and Bibliographic Formats -- drawing from a previous Discussion paper, a somewhat pro forma addition of rapidly becoming standard options to convey relationship data.

Proposal No. 2025-02: Redefining Subfield $b in X00 Fields in the MARC 21 Authority and Bibliographic Formats -- drawing from a previous Discussion paper, modifies the definition of X00 $b to expand beyond the current Western focus of what are more colloquially considered regnal numbers.

Discussion Paper No. 2025-DP01: Defining a New Subfield for Context of Transcribed Title Statement in Field 245 of the MARC 21 Bibliographic Format -- an exploration of a new 245 $z to provide a means of recording contextual information for titles, particularly those with "harmful language" (as articulated in the paper); this paper takes up, with a new solution, the topic previously explored in Discussion Paper 2024-DP02. The prior paper engendered extensive discussion and a variety of perspectives on this paper would be welcome.

Discussion Paper No. 2025-DP02: Adding a Code for Remote Sensing Image to Fields 008/25 and 006/08 (Maps) in the MARC 21 Bibliographic Format -- an exploration of expanding 008/006 coding to include "remote sensing image" as an option. I will show my hand that it seems the 007 field already supports identification of "remote sensing image" as a specific material designation in the 007/01 position. Guidance and perspectives on whether addressing this in the 008/006 would serve a sufficiently unique purpose or if it is unnecessarily duplicative would be welcome.

Discussion Paper No. 2025-DP03: Defining Field 655 (Index Term-Genre/Form) in the MARC 21 Holdings Format -- an exploration of adding field 655 to the Holdings format to address Genre/Form terms applicable to specific items of a manifestation (nominally, Genre/Form considerations are outside the scope of CC:DA but I welcome perspectives to provide contributions to MAC as general practitioners).

Discussion Paper No. 2025-DP04: Redefining Subfield $7 to Accommodate its Use with Subfield $g in Fields 856 and 857 of the MARC 21 Formats -- an exploration of modifying the definition of 856 $7 and 857 $7 to address the prior addition of $g to those fields; $g being a subfield to which the $7 (Access status) could apply.
