abstract = "We prove that for any $\epsilon$ {\textgreater} 0 there is k($\epsilon$) such that for any prime p and any integer c there exist k ≦ k($\epsilon$) pairwise distinct integers xi with 1 ≦ xi ≦ p$\epsilon$, i = 1,...,k, and such that ∑i=1k1/xi ≡ c (mod p). This gives a positive answer to a question of Erdos and Graham.",
