Lewis & Short

ŭbī-quē, adv., wherever, wheresoever, in any place whatever, anywhere, everywhere: quicumque ubique sunt, etc., Plaut. Bacch. 5, 1, 1: illud, quicquid ubique Officit, evitare, Hor. S. 1, 2, 60: litterae, quae ubique depositae essent, Liv. 45, 29, 1: tum navium quod ubique fuerat, in unum locum coëgerant, Caes. B. G. 3, 16: quod ubique habeat frumenti ac navium, ostendit, id. B. C. 2, 20: onerarias naves, quas ubique possunt, deprehendunt, id. ib. 1, 36; cf. id. ib. 3, 112; Cic. Verr. 2, 4, 4, § 7; cf. id. ib. 2, 4, 59, § 132: nec quidquid ubique est Gentis, Verg. A. 1, 601: studendum est semper et ubique, Quint. 10, 7, 27; so (with semper) id. 1, 1, 29; 3, 9, 5; 11, 1, 14: crudelis ubique Luctus, ubique pavor, Verg. A. 2, 368: longa mora est, quantum noxae sit ubique repertum, Enumerare, Ov. M. 1, 214: ubique versus, Lact. Opif. 5, 11.
So the phrase, freq. in Cic., omnes, qui ubique sunt, for an unlimited number, all wherever they may be, all in the world: ceteri agri omnes qui ubique suntdecemviris addicentur, Cic. Agr. 2, 21, 57; cf.: aut Epicurus, quid sit voluptas, aut omnes mortales qui ubique sunt nesciunt, id. Fin. 2, 3, 6; 2, 4, 13; id. Tusc. 1, 15, 35; id. N. D. 2, 66, 164; id. Div. 2, 63, 129; 2, 44, 93; id. Fin. 4, 27, 74; id. Verr. 2, 5, 67, § 172; id. Phil. 10, 5, 12.
Cf. without omnes: utinam qui ubique sunt propugnatores hujus imperii, possent in hanc civitatem venire, etc., Cic. Balb. 22, 51: quae res itineris ubique nos comitantur, everywhere on the journey, App. M. 1, p. 113, 8.
Note: The adv. ubique is to be distinguished from ubi with the enclitic -que, each retaining its force, as in Plaut. Bacch. 1, 1, 36; id. Merc. 5, 1, 11; id. Rud. 2, 3, 58; Cat. 63, 46; Sall. C. 21, 1; Liv. 36, 2, 5; Hor. S. 2, 2, 84.
