Books can now be obtained by anyone.
Literal
Books [topic-は], currently, everyone-[emphatic-も]-[subject-が] hand-[into-に] put [nominalizer-こと]-[subject-が] can-do.
A phrasing of 'books are available to everyone.' 誰もが ('everyone,' literally 'anyone-also') marks the quantifier subject with an emphatic も + が. 手に入れる ('to obtain,' the transitive counterpart of 手に入る) is nominalized with こと, giving 手に入れることができる = 'can obtain.' This is the explicit ~ことができる potential construction.
