One edition with two volumes

[L.]

Hello,

Local edition of Thai Horse by William Diehl was published in two volumes. This is the link to volume #1 on Goodreads.

Тай Хорс, Том #1

Volume #2 is not on Goodreads, but I can provide the info on it. Should the two volumes be combined with the main entry for Thai Horse as one book as is with this edition of Insomnia for example? Безсъние #1 и #2

Thank you.

[L.]

Bump.
