    (a) When the trustees determine to commence constructing the building, purchasing a site or a building, remodeling, repairing, or improving an existing library building, erecting an addition to an existing library building, or purchasing the necessary equipment for the library, they may then revise the plan or adopt a new plan and provide estimates of the costs of the revised or new plan.

economically procurable from only one source, such as for the purchase of magazines, books, periodicals, pamphlets, and reports.
    Contracts for emergency expenditures are also exempt from competitive bidding when the emergency expenditure is approved by 3/4 of the members of the board.
    The board shall require from the bidders security for the performance of the bids determined by the board pursuant to law. The trustees may let the contract or contracts to one or more bidders as they determine.
