A first impression of Hainsworth's and Churches' bibliography

I notice that Hainsworth and Churches (The Anglo-Dutch Naval Wars 1652-1674)have pretty complete coverage of the literature, with several, major exceptions. The greatest omissions are the two books by Dr. Johan E. Elias: Schetsen Uit de Geschiedenis van Ons Zeewezen (6 volumes) and De Vlootbouw in Nederland in de Eerste Helft der Zeventiende Eeuw, 1596-1655. Another omission is J.C. de Jonge's 6-volume work Geschiedenis van het Nederlandsche Zeewezen (5 volumes). The latter work is mainly useful for the appendices, but the text is worth scanning, at the minimum. They were able to use sources to which I have not found access, such as Barlow's journal. I do have many of the others, but not all, by any means.
