Dear colleagues,

We are cataloging one book, 4th edition. The original author has passed away. There is a different author in the 100 field. To link the current edition, based on RDA, a new work,  with the previous editions, is it better to use 700 with |t or 775. LC’s PPT example used 700 While checking the definition of 775, seems it can also be used

Which one is better or there is actually no difference? (I don’t see any difference in the indexing part. But potential record display might be different.)
