Hue, there are a few publications that listed marine non-directional beacons (NDB's), the most common one being the annual "Radio Navigational Aids" published by the United States Navy Hydrographic office. I have a number of these from the war years and I occasionally see them offered on the E place. By 1975, it appears to have been taken over by the Defense Mapping Agency Hydrographic Center.

The Yaquina Head Light Station you mentioned was sequenced with the Cape Arago and Columbia River (lightship) beacons, all on 304 KHz. In later years, Cape Blanco, Cape Disappointment and Wilapa Bay were added to the sequenced group.

While almost all of the marine beacons are gone, some live on as aeronautical NDB's, of which there are still thousands worldwide. There is a dedicated group of DXers that chase them and an online database (updated daily) that lists all active ones as well as many decommissioned NDB's going back to the 1990's. Reception distances can be surprising. Here on the West coast, Australian NDB's are occasionally heard, one as far as 8,000+ miles away, not bad for 25 watts on 486 KHz.

Regards to all.
